Test operation mode
(5) Option unit
Function
Absolute position
detection system
Encoder pulse output
High-resolution encoder of 131072 pulses/rev is used as a servo motor encoder.
Automatically adjusts the gain to optimum value if load applied to the servo motor
shaft varies.
MELSERVO-J2M detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Suppresses high-frequency resonance which occurs as servo system response is
increased.
Suppresses vibration of 1 pulse produced at a servo motor stop.
Forced stop (EM1) can be automatically switched on internally to invalidate it.
Servo motor torque can be limited to any value.
Disconnect forced stop (EM1) to bring the servo motor to a forced stop state, in
which the servo is switched off and the dynamic brake is operated.
In the servo-off or alarm status, this signal is disconnected.
When an alarm occurs, they are disconnected, independently of the base circuit
status.
It is possible to use it to excite an electromagnetic brake.
Servo status is output in terms of voltage in real time.
Used when the built-in regenerative brake resistor of the unit does not have
sufficient regenerative capability for the regenerative power generated.
Can simulate machine motions on a personal computer screen on the basis of the
machine analyzer results.
Can simulate machine motions on the basis of the machine analyzer results.
JOG operation and positioning operation are possible.
Merely setting a home position once makes home position return unnecessary at
every power-on.
Battery unit MR-J2M-BT is necessary.
The encoder feedback is output from enhancing IO unit MR-J2M-D01 by the
A B Z phase pulse. The number of pulses output by the parameter can be
changed.
