690+ Series Frequency Inverter
REFERENCE STOP
This function block holds all the parameters
concerning the stopping method of the
Inverter.
The stopping methods of the Inverter are
described in more detail in the Installation
Product Manual, Chapter 4: “Operating the
Inverter” - Starting and Stopping Methods..

Parameter Descriptions
RUN STOP MODE
Range: Enumerated - 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
3 : STOP RAMP
When RUN RAMP is selected the Inverter 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
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
Range: 0.00 to 100.00 %
Threshold for zero speed detection used by stop sequences.
STOP DELAY
Range: 0.000 to 30.000 s
Sets the time at which the Inverter 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.
FAST STOP MODE
Range: Enumerated - see below
Selects stopping mode used during a fast stop, two options ramped or coast.
Enumerated Value
:
Stopping Mode
0 : RAMPED
1 : COAST
FAST STOP LIMIT
Range: 0.0 to 3000.0 s
Maximum time that the Inverter will try to Fast Stop, before quenching.
FAST STOP TIME
Range: 0.0 to 600.0 s
Rate at which the SPEED DEMAND is ramped to zero (see REFERENCE function block)
FINAL STOP RATE
Range: 12 to 4800 Hz/s
Rate at which any internally generated setpoint trims are removed. For example, the trim due to
the slip compensation block.
