3.2.8 Automatic Tuning of Analog (Speed, Torque) Reference Offset
(Fn009)
This function measures the amount of offsets and adjusts the reference voltage auto-
matically. The amount of offsets measured is saved in the SERVOPACK.
Note: This function cannot be used when a position loop has been formed with a host control-
ler. Use the manual servo turning of speed reference offset (Fn00A) function or the man-
ual servo turning of torque reference offset (Fn00B) function to adjust the reference
voltage.
(1) Preparation
The following conditions must be met to adjust the offsets of speed or torque analog
reference automatically.
• The write prohibited setting (Fn010) must not be set to write-protect parameters.
• The servomotor power must be OFF.
(2) Operating Procedure
Use the following procedure.
