Parameter Descriptions
RUN STOP MODE
PREF: 102.01
Default: 0
Range: See below
Selects stopping mode that the controller will use once the run command has been removed. The choices are:
Enumerated Value
:
Stopping Mode
0 : RUN RAMP
1 : COAST
2 : DC INJECTION (only Volts/Hz control mode)
3 : STOP RAMP
When RUN RAMP is selected the Drive will decelerate using the reference ramp deceleration time, provided it is non zero.
When COAST is selected the motor will free-wheel. When DC INJECTION is selected the motor is stopped by applying dc
current. When STOP RAMP is selected the motor will decelerate in STOP TIME.
STOP TIME
PREF: 102.02
Default: 10.0 s
Range: 0.0 to 600.0 s
Rate at which the demand is ramped to zero after the ramp has been quenched.
STOP ZERO SPEED
PREF: 102.03
Default: 0.10 %
Range: 0.00 to 100.00 %
Threshold for zero speed detection used by stop sequences.
STOP DELAY
PREF: 102.04
Default: 0.500 s
Range: 0.000 to 30.000 s
Sets the time at which the Drive holds zero speed before quenching after a normal stop or a jog stop. This may be particularly
useful if a mechanical brake requires time to operate at zero speed, or for jogging a machine to position.
