Program features 65Note: Jogging is not operational when the drive start command is on, or if the drive isin local control.Note: The ramp shape time is set to zero during jogging. Scalar motor controlIt is possible to select scalar control as the motor control method instead of DirectTorque Control (DTC). In scalar control mode, the drive is controlled with a frequencyreference. However, the outstanding performance of DTC is not achieved in scalarcontrol.It is recommended to activate the scalar motor control mode in the followingsituations:• In multimotor drives: 1) if the load is not equally shared between the motors, 2) ifthe motors are of different sizes, or 3) if the motors are going to be changed aftermotor identification (ID run)• If the nominal current of the motor is less than 1/6 of the nominal output current ofthe drive• If the drive is used without a motor connected (for example, for test purposes)• If the drive runs a medium-voltage motor through a step-up transformer.In scalar control, some standard features are not available.8-9 x 0 1 Normal operation overrides the jogging. Drive follows thespeed reference.9-10 x 0 0 Drive decelerates to zero speed along the active decelerationramp.10-11 x 0 0 Drive is stopped.11-12 x 0 1 Normal operation overrides the jogging. Drive accelerates tothe speed reference along the active acceleration ramp.12-13 1 1 1 Start command overrides the jog enable signal.13-14 1 1 0 Drive decelerates to the jogging speed along thedeceleration ramp of the jogging function.14-15 1 1 0 Drive runs at the jogging speed.15-16 x 0 0 Drive decelerates to zero speed along the deceleration rampof the jogging function.Phase JogcmdJogenableStartcmd Description
