MOTOR
ROTATION
(Motor Rotation)
This parameter allows the user to change the
direction of the motor rotation. As an example, if
the car controller is commanding the up
direction and the car is actually going in a down
direction, this parameter can be changed to
allow the motor rotation to match the car
controller command.
FORWARD
− forward
− reverse

ENCODER
CONNECT
(Encoder Connection)
This parameter allows the user to electronically
switch A and /A signals from the encoder
without moving any wiring.
FORWARD
− forward
− reverse
Y Y
SPD REF
RELEASE
(Speed Reference Release)
The user can select when the Speed Reference
Release signal is asserted:
• If the user does not want the drive to wait for
the mechanical brake to be picked then SPD
REF RELEASE can be made equal to REG
RELEASE;
• If the user does want the drive to wait for the
brake to be picked then SPD REF
RELEASE is not asserted until an internal
BRAKE PICKED signal becomes true. The
user must have one logic input set to Mech
Brk Pick – see page 61.
REG
RELEASE
− reg release
− brake picked
Y Y
CONT
CONFIRM
SRC
(Contactor Confirm Source)
This switch selects if hardware confirmation of
motor contactor closure is necessary before
drive attempts to pass current through motor. If
hardware confirmation is available set to
EXTERNAL TB and select the Contact Cfirm
signal on a logic input terminal – see page 61.
NONE
− external tb
− none

PreTorque
SOURCE
(Pre-Torque Source)
This switch determines the source of a pre
torque command and how it is used.
Pre-torque is the value of torque that the drive
should produce as soon as the speed regulator
is released to prevent rollback due to
unbalanced elevator loads.
This ‘priming’ of the speed regulator is done with
the pre-torque command, which is used when
the speed regulator release is asserted.
The two possible sources for the pre-torque
command are following:
• serial channel
• analog channel
The serial channel is the RS-422 serial port on
the Customer Interface PCB. The analog pre-
torque signal is bipolar (±10V). Available with
the analog channel is a Pre-Torque Command
Multiplier (PRE TORQUE MULT (A1)) and Pre-
Torque Bias (PRE TORQUE BIAS(A1)). These
parameters are used to scale the user’s analog
pre-torque command to the proper range for use
by the drive software.
NONE
− none
− analog input
− serial
