1.3 Function list
The following table lists the functions of this servo. For details of the functions, refer to the reference field.
Function Description Reference
Slight vibration suppression
control
Suppresses vibration of 1 pulse produced at a servo motor stop. Section 6.5
Real-time auto tuning
Automatically adjusts the gain to optimum value if load applied to the servo
motor shaft varies.
Section 6.2
Section 6.3
Parameter No.9
Torque limit Servo motor torque can be limited to any value.
Parameter No.10
Parameter No.11
External forced stop signal
automatic ON
Forced stop (EM1) can be automatically switched on internally to invalidate it. Parameter No.23
Test operation mode
Servo motor can be run from the operation section of the servo amplifier
without the start signal entered.
Section 4.4
Servo configuration software
Using a personal computer, parameter setting, test operation, status display,
etc. can be performed.
