7b.6.2 Drive Parameters

The following is a list of the parameters in the drive. Also included are an explanation of the
parameter and how it should be set. Refer to Section 6b.3.3 for the initial programming of the
drive.

Description
This parameter tells the drive what the rated speed of the car is. It is
used to display the speed of the car and the speed command in FPM
at the Elevator Data D1 menu.
This parameter tells the drive the RPM the motor should be turning
when the car is turning at rated speed.
This parameter controls the responsiveness of the speed regulator. It
sets the band width of the speed regulator. Larger numbers make the
system more responsive.
This parameter tells the drive the moment of inertia of the system.
See section 7b.5 for set up procedure.
This parameter controls the frequency of the inner speed loop
crossover in the speed regulator.
This parameter sets the amount of gain for the speed regulator to
use in the Gain Reduce mode. It is a percentage, and modifies the
Response parameter.
This parameter sets the speed at which the Gain Reduce mode
becomes active.
This parameter is controls the Tach Rate Gain function. It should not
be used except to tune out vibrations which cannot be removed by
any other means. Contact O. Thompson before activating.
This parameter sets the phase margin of the speed regulator,
assuming a pure inertial load.
This parameter sets the ramp down of the motor torque after the
drive is stopped.
This parameter sets the maximum amount of time the drive will wait
for the main contactor's auxiliary contact before declaring a
Contactor Fault.
If the Brake Pick fault is enabled, this parameter sets the maximum
amount of time the drive will wait for the brake's contactor's auxiliary
contact before declaring a Brake Pick Fault. Not activated on O.
Thompson controls.
If the Brake Hold fault is enabled, this parameter sets the maximum
amount of time the drive will wait for the brake's brake hold feedback
to match the brake pick command before declaring a Brake Hold
Fault. Not activated on O. Thompson controls.
This parameter sets the speed level at which an Overspeed fault is
declared. Set in conjunction with Overspeed Time.
The amount of time the overspeed condition must exist before an
Overspeed fault is declared. Set in conjunction with Overspeed
Level.
