condition
Gain switching condition
0 Fixed to 1st gain Fixed to the 1st gain (Pr1.00 to Pr1.04).
1 Fixed to 2nd gain Fixed to the 2nd gain (Pr1.05 to Pr1.09).
2
With gain
switching input
• 1st gain when the gain switching input (GAIN) is open.
• 2nd gain when the gain switching input (GAIN) is connected to COM-.
*
If no input signal is allocated to the gain switching input (GAIN), the 1st gain is fixed.
3
Torque
command is
large
• Shift to the 2nd gain when the absolute value of the torque command exceeded (level +
hysteresis) (%) previously with the 1st gain.
• Return to the 1st gain when the absolute value of the torque command was kept below (level
- hysteresis) (%) previously during delay time with the 2nd gain.
4
Variation
of speed
command is
large
• Valid only during velocity control.
• Shift to the 2nd gain when the absolute value of the speed command variations exceeded
(level + hysteresis) (10r/min/s) previously with the 1st gain.
• Return to the 1st gain when the absolute value of the speed command variations was kept
below (level - hysteresis) (10r/min/s) during delay time previously with the 2nd gain.
*
The 1st gain is fixed while the velocity control is not applied.
5
Speed
command is
large
• Valid for position, velocity and full-closed controls.
• Shift to the 2nd gain when the absolute value of the speed command exceeded (level +
hysteresis) (r/min) previously with the 1st gain.
• Return to the 1st gain when the absolute value of the speed command was kept below (level
- hysteresis) (r/min) previously during delay time with the 2nd gain.
6
Position
deviation is
large
• Valid for position and full-closed controls.
• Shift to the 2nd gain when the absolute value of the positional deviation exceeded (level +
hysteresis) (pulse) previously with the 1st gain.
• Return to the 1st gain when the absolute value of the positional deviation was kept below
(level - hysteresis) (pulse) previously over delay time with the 2nd gain.
*
Unit of level and hysteresis (pulse) is set as the encoder resolution for positional control
and feedback scale resolution for full-closed control.
7
Position
command
exists
• Valid for position and full-closed controls.
• Shift to the 2nd gain when the positional command was not 0 previously with the 1st gain.
• Return to the 1st gain when the positional command was kept 0 previously during delay
time with the 2nd gain.
8
Not in
positioning
complete
• Valid for position and full-closed controls.
• Shift to the 2nd gain when the positioning was not completed previously with the 1st gain.
• Return to the 1st gain when the positioning was kept in completed condition previously
during delay time with the 2nd gain.
9
Actual speed is
large
• Valid for position and full-closed controls.
• Shift to the 2nd gain when the absolute value of the actual speed exceeded (level +
hysteresis) (r/min) previously with the 1st gain.
• Return to the 1st gain when the absolute value of the actual speed was kept below (level -
hysteresis) (r/min) previously during delay time with the 2nd gain.
10
Position
command
Actual speed
• Valid for position and full-closed controls.
• Shift to the 2nd gain when the positional command was not 0 previously with the 1st gain.
• Return to the 1st gain when the positional command was kept at 0 during the delay
time and the absolute value of actual speed was kept below (level - hysteresis ) (r/min)
previously with the 2nd gain.
Set up the triggering condition of gain switching for position control.
