2.2 Characteristics of "PY2" Servo Amplifier
This section explains the characteristics of the "PY2" amplifiers.
• The volume is about half that of conventional models
About 40% to 65% smaller in terms of volume than the “PY”, ”PZ” and ”PE” series.
PY2A015 (to 300 W) : About 45%
PY2A030 (to 1 kW) : About 65%
PY2A050 (to 2 kW) : About 45% (Note: "PY" is assumed to be 100%.)
• Unified height and depth
The height of the amplifier applicable to 30 W to 2 kW motors is kept at to 168 mm (excluding the
mounting fitting) and the depth at 135 mm.
• Front or rear installation is selectable
Although only rear installation is usually available for a small Servo Amplifier, both front and rear
installations can be selected for the "PY2" or "PY" type.
(Rear installation is standard for the "PY2" on shipment.)
• All amplifier I/O wirings are changed to the connector type
The terminals of the high-voltage parts, which used to be the terminal board type on our conventional
"PY" and "PZ" series, are changed to the connector type. This improves operability when installing or
maintaining the Servo Amplifier.
• The leakage current has been reduced to about half that of conventional models
Measures to reduce leakage current are taken on the "PY2" amplifier, reducing it to about half that of
our conventional "PY" or "PZ" series.
When a 2 m cabtyre cable is used for the motor power line:
• 15A, 30A 0.5 mA or less
• 50A 1.5mA or less
• Additional tuning function
In addition to “Offline auto tuning” function, “Online auto tuning” and “Auto notch filter tuning” functions
are available.
