REFERENCE STOP
SETUP::SEQ & REF::REFERENCE STOP
This function block holds all the parameters concerning the stopping method of the Drive.
The stopping methods of the Drive are described in more detail in Chapter 8: "Operating the Drive" - Starting and Stopping
Methods.
Parameter Descriptions
RUN STOP MODE
Selects stopping mode that the controller will use once the run command has been removed. The choices are:
Enumerated Value : Stopping Mode
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
Rate at which the demand is ramped to zero after the ramp has been quenched.
STOP ZERO SPEED
Threshold for zero speed detection used by stop sequences.
STOP DELAY
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.
