Drive commands supported by the Generic Drive communication profile

Name Description
STOP The drive decelerates the motor to zero speed according to the active deceleration ramp
(parameter 22.03 or 22.05).
START The drive accelerates to the set reference value according to the active acceleration ramp (Par.
22.02 or 22.04). The direction of rotation is determined by the sign of the reference value and the
setting of par. 10.03.
COAST STOP The drive coasts to stop, that is the drive stops modulating. However, this command can be
overridden by the Brake Control function, which forces the drive to decelerate to zero speed by the
active deceleration ramp. When the Brake Control function is active, Coast stop and Emergency
coast stop (OFF2) commands given after the Emergency ramp stop (OFF3) coast the drive to
a stop.
QUICK STOP The drive decelerates the motor to zero speed within the emergency stop deceleration time
defined with Par. 22.07.
CURRENT LIMIT The drive decelerates the motor to zero speed according to the set current limit (Par. 20.03) or
STOP (CLS) torque limit (20.04), whichever is first reached. The same procedure is valid in case of a Voltage
Limit Stop (VLS).
INCHING1 With this command active, the drive accelerates the motor to Step reference 3 (defined with Par.
12.04). After the command is removed, the drive decelerates the motor to zero speed.
Note: The speed reference ramps are not effective. The speed change rate is only limited by the
current (or torque) limit of the drive.
Note: Inching 1 takes priority over Inching 2.
Note: Not effective in Scalar control mode.
INCHING2 With this command active, the drive accelerates the motor to Step reference 4 (defined with Par.
12.05). After the command is removed, the drive decelerates the motor to zero speed.
Note: The speed reference ramps are not effective. The speed change rate is only limited by the
current (or torque) limit of the drive.
Note: Inching 1 takes priority over Inching 2.
Note: Not effective in Scalar control mode.
RAMP OUT ZERO When active, forces the output of the reference function generator to zero.
RAMP HOLD When active, freezes the reference function generator output.
FORCED TRIP Trips the drive. The drive will indicate fault FORCED TRIP.
RESET Resets an active fault.
Fieldbus control
