Notes:
• Jogging is not available when the drive is in local control.
• Jogging cannot be enabled when the drive start command is on, or the drive
started when jogging is enabled. Starting the drive after the jog enable switches
off requires a fresh start command.
WARNING! If jogging is enabled and activated while the start command is on,
jogging will activate as soon as the start command switches off.
• If both jogging functions are activated, the one that was activated first has priority.
• Jogging uses the speed control mode.
• Ramp shape times (parameters 23.16...23.19) do not apply to jogging
acceleration/deceleration ramps.
• The inching functions activated through fieldbus (see
bits 8...9) use the references and ramp times defined for jogging, but do not
require the jog enable signal.

along the selected deceleration ramp (parameters
