Bit 0: Switching ON / OFF
This bit is used in combination with other bits to enable operation of the drive. When this bit is set
to 0 during operation, the drive performs a ramp stop.
Bit 1: Coast stop command
This bit is used to request a coast stop to be executed. When it is set to 0 during operation, the drive
performs a coast stop.
Bit 2: Quick stop command
This bit is used to request a quick stop to be executed. When it is set to 0 during operation, the drive
quickly ramps down to zero speed and stops.
Bit 3: Enabling of operation
This bit is used in combination with other bits to enable operation of the drive. When it is set to 0
during operation, the drive performs a coast stop.
Bit 4: Enabling of ramp generator
This bit is used in combination with other bits to enable operation of the drive. When it is set to 0
during operation, the drive quickly decelerates to zero speed.
Bit 5: Freezing of ramp generator
This bit can be used to freeze the setpoint value used by the drive. The value is frozen if this bit is
set to 0. If the bit is 1, the setpoint value provided by the master is continuously updated.
Bit 6: Enabling of setpoint value
This bit can be used to disable the fieldbus setpoint value. If this bit is set to 0, the option board
ignores the setpoint value by the master and instead uses a setpoint value of 0. During operation, if
this bit is set to 0, the drive decelerates to a standstill.
