RUN STOP TIME
Sets deceleration rate for the Stop ramp operation.
RUN STOP LIMIT
Sets the maximum time the drive will allow the Stop function to operate, if the drive has not
reached zero speed in this period the drive will coast to a stop. If USE SYSTEM RAMP =
TRUE then timer is started once the o/p of the system ramp of local ramp reaches zero.
FAST STOP TIME
Sets deceleration rate for the Fast Stop ramp operation.
FAST STOP LIMIT
Sets the maximum time the drive will allow the Fast Stop function to operate, if the drive
has not reached zero speed in this period the drive will coast to a stop.
USE SYSTEM RAMP
Forces the drive to quench the input to the system ramp / local ramp and wait for the ramp
output to reach zero before doing a normal stop.
NOTE: Not applicable for Fast Stop.
Note the System Ramp is by-passed if any of the following conditions are true:-
Ramp Hold, Ramp External Reset, Ramp Quench or Speed Loop Test Mode.
PRE-START DELAY
Delays the enabling of the drive to allow time for an o/p contactor to close before current is
passed. This delay is only added if the pilot output is open.
READY DELAY
See below for a more detailed description.
CONTACTOR DELAY
Sets the time during which the drive will maintain zero speed after the motor has stopped.
NOTE: This does not effect the operation of the pilot output. The term contactor delay
comes from the 590 DC drive.
PILOT 590 MODE
If TRUE the contactor / pilot output mimics the behaviour of the 590 DC Drive. The
contactor is only closed while the drive is in RUN mode. In this mode the drive always
inserts a delay of " PRE-START DELAY " before enabling the stack, this is to allow time for
the contactor to close. A better way of doing this is to use an auxiliary contact into the
Enable Input.
If FALSE the contactor is closed on power-up and only opened if the drive trips.
STOP ZERO SPEED
Sets the threshold at which the contactor delay timer is started.
PROG STOP I-LIM
Sets the current limit used during a program stop. This will not override the inverse time
output.
