Set up the time constant of 1st delay filter which affects the input of torque feed forward.
zero positional deviation is impossible in actual situation because of disturbance torque. as with
the velocity feed forward, large torque feed forward filter time constant decreases the operating noise
but increases positional deviation at acceleration change point.

2nd gain when the gain switching input is connected to com- .
If no input signal is allocated to the gain switching input, the
1st gain is fixed.

Torque command is

⚫
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.

Speed command is
large
⚫
Valid for position and speed 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 control.
⚫
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)[r/min]previously during delay time with the 2nd
gain.
Unit of level and hysteresis [pulse] is set as the encoder
resolution for positional control.

position command
exists
⚫
Valid for position control.
⚫
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 control.
⚫
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.

Actual speed is

Valid for position control.

Shift to the 2nd gain when the absolute value of the actual
speed exceeded (level + hysteresis) (r/min) previously with
the 1st gain.
