The jogging function operates on a 2 ms time level.
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
) 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.
