 PREFACE 
The PY series Servo Amplifier is applicable to a wide range of applications from small to medium 
capacity thanks to its multiple functions, high performance, downsizing and high cost performance.   
The PY2 was developed as an upgraded version of this PY series to satisfy customer needs for 
further downsizing. 
The PY2 Servo Amplifier features the same performance as the PY series, on which it is based, 
with only the size reduced.    The small and high performance PY2 Servo Amplifier is useful for a 
large number of customers in applications requiring space saving. 
This Users Manual explains the functions, wiring, installation, operation, maintenance and 
specifications of the PY2 Servo Amplifies and our Servomotors. 
To completely utilize all functions of the PY2 series, read this manual carefully before use to 
ensure proper operation. 
After reading this manual, keep it handy so that it can be referred to by anyone at anytime. 
 
 
 
 
 
 
 
 
 
 
 
 
In this manual,   
AC Servomotor is sometimes abbreviated to Servomotor or Motor.   
AC Servo Amplifiers to Servo Amps. or Amps.. 
Also, Wiring-saved incremental encoders and Request signal-unavailable 
absolute encoders are sometimes abbreviated to Encoders and Wiring-saved 
incremental encoders, Request signal-unavailable absolute encoders and 
Request-available absolute sensors to Sensors.

  International Standard Compliance 
The “PY2” Servo Amplifier complies with the following International standards. 
 
International standardStandard No. 
TÜV EN50178 
UL UL508C 
CUL UL508C 
Low Voltage Directive EN50178 
EMC Directive  EN55011 
 
 
Working Environment 
Since the working environment for the “PY2” Servo Amplifiers must be pollution level 2 or above (i.e. level 1 
or 2) as specified in EN50178,    be sure to use them in a pollution level 1 or 2 environment. 
 
 
Power Supply 
The “PY2” Servo Amplifiers must be used under the conditions specified in overvoltage category II, EN 
50178.    Use a reinforced insulation transformer conforming to the EN Standard for power supply input. 
For the interface, use a DC power supply whose input and output sections have reinforced-insulation.
