Name and Function
Serial communication time-out selection
Used to choose the time-out period of communication protocol.
Setting
0 No time-out check
Time-out check period setting
1 to 60
Check period
Feed forward gain
Used to set the feed forward gain.
At the setting of 100%, droop pulses during constant-speed
operation will be almost "zero".
Note that sudden acceleration/deceleration will increase overshoot.
As a guideline, set 1s or more as the acceleration/deceleration time
constant to the rated speed when the feed forward gain is set to
100%. When setting this parameter, always set auto tuning
(parameter No.3) to "Not executed".
Override offset
Used to set the offset voltage to analog override.
Torque limit offset
Used to set the offset voltage to analog torque limit (TLA).
For manufacturer setting
Must not be change
Internal torque limit 1
Used to limit servo motor-torque on the assumption that the
maximum torque is 100%. When 0 is set, torque is not produced.
Internal torque limit 2
Used to limit servo motor-torque on the assumption that the
maximum torque is 100%. When 0 is set, torque is not produced.
Made valid by switching on the internal torque limit selection (TL2).
Backlash compensation
Used to set the backlash compensation made when the command
direction is reversed.
This function compensates for the number of backlash pulses in the
opposite direction to the home position return direction. In the
absolute position detection system, this function compensates for the
backlash pulse count in the direction opposite to the operating
direction at power-on.
Analog monitor 1 (MO1) offset
Used to set the offset voltage of the analog monitor 1 (MO1) output.
Analog monitor 2 (MO2) offset
Used to set the offset voltage of the analog monitor 2 (MO2) output.
