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 23.16…23.19) do not apply to jogging
acceleration/deceleration ramps.
• The inching functions activated through fieldbus (see 06.01 Main control word,
bits 8…9) use the references and ramp times defined for jogging, but do not
require the jog enable signal.
10-11 x 0 1 Drive follows the speed reference.
11-12 x 0 0 Drive decelerates to zero speed along the selected
deceleration ramp (parameters 23.11…23.19).
12-13 x 0 0 Drive is stopped.
13-14 x 0 1 Drive accelerates to the speed reference along the selected
acceleration ramp (parameters 23.11…23.19).
14-15 x 0
-
>1 1 Drive follows the speed reference. As long as the start
command is on, the jog enable signal is ignored. If the jog
enable signal is on when the start command switches off,
jogging is enabled immediately.
15-16 0
-
>1 1 0 Start command switches off. The drive starts to decelerate
along the selected deceleration ramp (parameters
23.11…23.19).
When the jog command switches on, the decelerating drive
adopts the deceleration ramp of the jogging function.
16-17 1 1 0 Drive follows the jog reference.
17-18 0 1
-
>0 0 Drive decelerates to zero speed along the deceleration ramp
of the jogging function.
