5.2 Detailed list of parameters
Function
For manufacturer setting
Fully closed loop control - Position deviation error detection level - Unit selection
0: 1 kpulse unit
1: 1 pulse unit
The setting of this digit is used by servo amplifier with software version A1 or later.
For manufacturer setting
Set a numerator of electronic gear for the servo motor encoder pulse at the fully closed loop control.
Set the electronic gear so that the number of servo motor encoder pulses for one servo motor revolution is
converted to the resolution of the load-side encoder.
Page 524 Setting of feedback pulse electronic gear
This parameter is supported with software version A1 or later.
Setting range: 1 to 65535
Set a denominator of electronic gear for the servo motor encoder pulse at the fully closed loop control.
Set the electronic gear so that the number of servo motor encoder pulses for one servo motor revolution is
converted to the resolution of the load-side encoder.
Page 524 Setting of feedback pulse electronic gear
This parameter is supported with software version A1 or later.
Setting range: 1 to 65535
Robust filter selection
0: Disabled
1: Enabled
When "Enabled" is set, the machine resonance suppression filter 5 that is set in [Pr. PB51] is not available.
For manufacturer setting
Set the lost motion compensation for when reverse rotation (CW) switches to forward rotation (CCW) in
increments of 0.01% assuming the rated torque as 100%.
Setting range: 0 to 30000
Set the lost motion compensation for when forward rotation (CCW) switches to reverse rotation (CW) in
increments of 0.01% assuming the rated torque as 100%.
Setting range: 0 to 30000
Set the time constant of the lost motion compensation filter in increments of 0.1 ms.
If the time constant is "0", the torque is compensated with the value set in [Pr. PE44] and [Pr. PE45]. If the
time constant is other than "0", the torque is compensated with the high-pass filter output value of the set time
constant, and the lost motion compensation will continue.
Setting range: 0 to 30000
Set this when canceling unbalanced torque of vertical axis. Set this assuming the rated torque of the servo
motor as 100%. The torque offset does not need to be set for a machine not generating unbalanced torque.
The torque offset cannot be used for linear servo motors and direct drive motors. Set 0.00%.
The torque offset set with this parameter will be enabled in the position mode, velocity mode, and torque
mode. Input commands assuming torque offset for the torque mode.
Setting range: -10000 to 10000
Lost motion compensation selection
0: Disabled
1: Enabled
Unit setting of lost motion compensation non-sensitive band
