"PY2" Servo Amplifier Built-in Functions

This section describes the main built-in functions of the Servo Amplifier and additional functions specially for
the PY2 series.
The functions marked
● Position, speed and torque control
The above three types are controlled as a package and can be selected using the remote operator.
The control type can be changed during operation (velocity ↔ torque, position ↔ torque, position ↔
velocity).
● Regenerative processing function
A regenerative processing circuit is built into the system, which enables regenerative processing simply
by externally connecting a resistor to the amplifier.
Since no regenerative resistor is built in except for 50 A type amplifier, one is required to be externally
connected to the amplifier when regenerative processing is required.
● Dynamic brake function
When the main circuit power supply is cut off, the dynamic brake is actuated.
However, this brake is operated regardless of the main circuit power supply when an alarm occurs.
● Holding brake excitation timing output
The power supply to the holding brake is controlled with the timing of this output signal, thereby
preventing a self-weight fall of the gravitational shaft at an emergency stop.
Keep this output open when the system is not operated.
● Vibration restraining function
If a vibration occurs when this function is incorporated in the system, the parameters "BEF" and "LPF"
are set by the remote operator according to the vibration frequency, restraining the vibration.
offline, executing "auto notch filter tuning (Tune IBEF) at test mode can automatically set notch filter
frequency (IBF1). For more adequate setting, measure the oscillation frequency with an oscilloscope
on the current command monitor.
● Separation of control power and main circuit power
The control power and the main circuit power are separated.
When an alarm or an emergency stop occurs, the main circuit power alone can be cut off for safety, and
the control power can remain activated.
This enables the continuation of alarm output, making analysis and maintenance easy.
OP require the remote operator (see Chapter 7).
