3.2.9 Manual Servo-tuning of Speed Reference Offset (Fn00A)
With this function, the speed reference offset can be adjusted by manually inputting
the amount of the offset. Use this function in the following cases.
• To adjust position error to zero when a position loop is formed with the host con-
troller and the servomotor is stopped by servolock.
• To deliberately set the offset amount to some value.
• To check the offset amount calculated in the automatic adjustment mode.
(1) Preparation
The following conditions must be met to adjust the offsets of speed reference manu-
ally.
• The write prohibited setting (Fn010) must not be set to write-protect parameters.
• The main circuit power supply must be ON.
• All alarms must be cleared.
• The hardwire baseblock (HWBB) must be disabled.
• When an absolute encoder is used, the SEN signal is ON (high level).
(2) Operating Procedure
Use the following procedure.
