Parameter Descriptions
STOP TIME
Range: 0.1 to 600.0 SECS
Time to reach zero speed from 100% set speed in normal stop mode (C3 OFF).
STOP LIMIT Range: 0.0 to 600.0 SECS
Delay time limit to allow normal stop action (regenerative breaking) to achieve zero speed
before drive quench and coast stop. The timer is triggered by Start command (C3) going low.
CONTACTOR DELAY Range: 0.1 to 600.0 SECS
This defines the time between the drive reaching STOP ZERO SPEED (Tag No. 29) and the
contactor being opened. This is particularly useful during the jog cycle to prevent multiple
operations of the main contactor.
If STOP ZERO SPEED is
≥
0.25%, the drive will be quenched during the contactor delay.
The Contactor delay is overridden by Enable (C5).
Maintain zero speed during contactor delay.
If STOP ZERO SPEED is < 0.25%, the drive will not be quenched until CONTACTOR DELAY
expires.
PROG STOP TIME Range: 0.1 to 600.0 SECS
Time to reach zero speed from 100% set speed in program stop mode(B8 OFF).
PROG STOP LIMIT Range: 0.0 to 600.0 SECS
Delay time limit to allow program stop action (regenerative breaking) to achieve zero speed
before drive quench and coast stop. The timer is triggered by Program Stop command (B8)
going low.
PROG STOP I LIM Range: 0.00 to 200.00 %
Main current limit level in program stop mode assuming current limit not overridden by I Profile
or Inverse Time limits.
STOP ZERO SPEED Range: 0.00 to 100.00 %
Zero speed level in program stop and normal stop modes at which the contactor delay timer
starts timing-out. At the end of this delay the contactor is de-energised.
