EV–T100 TRANSISTOR MOTOR CONTROLLER,

Parameter Tables

GENERAL

This section must be used with the following sections of
this motor controller:

MENTS WITH A COMPUTER For
EV–100ZX And EV–T100 Motor Controllers,
2200 SRM 597

The EV–T100 series of control cards have an electronic
device called an EEPROM (Electrically–Erasable–
Programmable–Read–Only–Memory). The EEPROM
has a number of memory elements called registers.
These registers can have electronic data stored in them
to control an operation. The range of data that can be
stored in the registers is called a parameter. A parame-
ter is a measurement number that works with other mea-
surement numbers (parameters) to define a system. The
EEPROM in the control card is a control system for the
operation of the lift truck.

The EEPROM used in the EV–T100 series of control
cards has 128 registers.

WARNING

Each register in each control card has a range of
numbers so that the control card can be used on dif-
ferent models of lift trucks. This variation is needed
for lift trucks of different sizes and operating volt-
ages. Adjustment of the register to the wrong num-
ber for your lift truck model can cause the truck to
operate differently than normal. This different oper-
ation of the truck can cause an injury.

Do NOT adjust any of the registers without using the
parameters shown in this section.

NOTE: The Parameter Tables show the permitted
ranges and the default setting for each control function.
The Factory Set Parameters are the recommended set-

tings for new units. These settings will give satisfactory
performance for most applications.

Some functions can be adjusted within the permitted
range to change the lift truck operation for a specific
application. Adjustment of a register to a number that is
different than the factory setting is allowed, but follow
the instructions carefully and stay within the minimum
and maximum limits. Adjustments other than the facto-
ry settings will cause the lift truck to operate differently
and can cause increased wear of parts.

Parameters must be between the minimum and maxi-
mum numbers shown in the tables for your lift truck
model. Do NOT adjust a parameter to a number that is
NOT SHOWN in the correct table. Make sure you use
the correct table when you make adjustments. It is a
good procedure to check the parameter and compare the
parameter to the number in the table before making the
adjustment. The factory parameter, and the value (cur-
rent, time, etc.) for that parameter, are shown in the col-
umns indicated as Default. The minimum and maxi-
mum parameters and their values are shown in the col-
umns indicated as Permitted Range.

NOTE: Check the label at the top edge of each card case
to identify the control card on your lift truck. There are
some painted letters and numbers followed by other
numbers and letters on the lower part of the label. The
last two letters on the lower part identify the TYPE of
card installed. The table titles show these card types for
the EV–T100 motor controllers.

Make sure to read the WARNINGS and CAUTIONS in
this section including those in the tables. Also read the
WARNINGS and CAUTIONS in the following sec-
tions:

FUNCTION NUMBERS

CAUTION

Do not set the Field Weakening functions to any val-
ue other than the value shown for each function.
There can be traction motor damage if Field Weak-
ening is used with these motors that are not designed
for it.

NOTE: A control card that has the Field Weakening
functions can be installed on lift trucks that have traction
motors that are not designed for Field Weakening. The
Field Weakening functions are set to not operate on
these lift trucks.

The Function Numbers are code numbers for the differ-
ent parameters that can be set for the EV–T100 series
control cards. The Personal Computer or the Hand Set
must be used to adjust the parameters for the control
card. There is a description of the code numbers for the
different control cards in the Parameter Tables. These
Parameter Tables have the correct setting numbers for
the parameters on each control card.

CONTROL CARD, CHECKS AND
ADJUSTMENTS

A Personal Computer (PC) or a Hand Set is used to per-
mit Authorized Personnel to make the following
checks and adjustments:

•

Check the system status codes for both traction
and hydraulic pump SCR systems

•

Check for status codes that are not regular nor
constant

•

Check the state of charge of the battery on motor
controllers with type JH, JY, NH or NY control
cards

•

Check the hourmeter readings on the traction cir-
cuit and hydraulic pump SCR controllers

•

Monitor or adjust the following control func-
tions:

♦

Creep Speed

♦

Controlled Acceleration and 1A Time

♦

Current Limit

♦

Steering pump time delay and define signal
input (seat switch or directional switch)

♦

Plugging distance (Current)

♦

Accelerator pedal position, plug range or
disable

♦

1A drop out current or disable

♦

Field Weakening drop–out

♦

Field Weakening pick–up

♦

Regenerative Braking current limit

♦

Regenerative Braking drop–out

♦

Speed limit points (SL1, SL2 and SL3)

♦

Internal resistance compensation for battery
state of charge indication

♦

Battery voltage (36/48V is auto ranging)

•

Selection of type of card operation:

♦

Traction circuit with Field Weakening

♦

Traction circuit with Regenerative Braking
and Field Weakening

♦

High or low current limit for all of the above
functions

NOTE: Make sure to follow the procedures in the fol-
lowing sections:

REGISTER PARAMETERS
(See TABLE 1. and TABLE 2.)

Parameters must be between the minimum and maxi-
mum numbers shown. Do NOT adjust a parameter to a
number that is not shown in the correct table. Make sure
you use the correct table when you make adjustments. It
is a good procedure to check the parameter and compare
the parameter to the number in the table before making
the adjustment. The factory parameter, and the value
(current, time, etc.) for that parameter, are shown in the
columns indicated as Default. The minimum and maxi-
mum parameters and their values are shown in the col-
umns indicated as Permitted Range.

NOTE: Check the label at the top edge of each card case
to identify the control card on your lift truck. There are
some painted letters and numbers followed by other
numbers and letters on the lower part of the label. The

3

last two letters on the lower part identify the TYPE of
card installed. The table titles show these card types for
the EVT–100 motor controllers.

Make sure to read the WARNINGS and CAUTIONS
under each parameter description and in the section PA-
RAMETERS, CHECKS AND ADJUSTMENTS.

CAUTION

Do not set the Field Weakening functions without

checking the brand of traction motor on the truck.
There can be traction motor damage if Field Weak-
ening is used with motors that are not designed for it.

Field Weakening for these models is only available
on trucks that have the “Lenoir” brand traction mo-
tors. The control card that has the Field Weakening
functions can be installed on trucks without the “Le-
noir” brand traction motors.

Functions 22 through 26. These registers can be read with the Hand Set, but the data in them changes during
lift truck operation. Do NOT change the parameters in the registers for Function numbers 22 through 26.

Function 25 (temporary storage register for fault data) and Function 26 (temporary storage register for
battery charge data) must not be changed by the user to any number above zero. Any number above
zero can cause the instrument panel display to not operate correctly and the lift truck can become
disabled.

Functions 31 through 47 can be read and cleared with a Hand Set. These registers store the fault codes and
other data that the controller senses during the operation of the lift truck. These registers can only be reset to
zero. The PC software program automatically resets these registers to zero.

Functions 48 through 62 enable the lift truck to be set to four performance levels by the operator. If the customer
does not want this function available to the operator, a service person can set all four levels to the same setting.
Each time the operator pushes the button on the instrument panel, the performance level will increase by one
step.
