  2.1  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      require the remote operator (see Chapter 7). 
 
●  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...

●  Servo tuning support function   
When the remote operator sets a mode, the load inertia is automatically estimated and a proper 
parameter is set.    There are two different kind of tuning methods: one is “Offline auto tuning” executed 
at test mode when offline, and the other is “Online auto tuning” estimating appropriate gain and 
changing the gain at real time during operation.   
 
●  Electric gear function 
For a position control type, the...

●  Power supply type selection function (200 VAC input type) 
Either a 3-phase, 200 VAC type or the single phase, 200 VAC type main power supply can be selected.   
After selecting either one, simply turn the control power supply on again, no other parameter settings 
are necessary.    (Since some types of motors have different 3- or single-phase properties, refer to the 
combination specifications in Section 9.) 
 
●  Applicable to wiring-saved...

Additional function specially for the PY and PY2 series (compared to PZ amplifiers) 
In addition to the various control functions provided in the PZ series, the following functions have been 
added to the PY and PY2 series   
 
1.  Control mode switching function     
This function is for switching the control mode without power shutdown. 
 
2.  Internal velocity command function 
The amplifier has three types of velocity commands, and this...

  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...

•  Supports various types of power supplies 
The “PY2” Servo Amplifier supports 200 VAC 3-phase, 200 VAC single-phase and 100 VAC 
single-phase types of power supplies. 
Switching between 200 VAC 3-phase and 200 VAC single-phase is possible by simply changing the 
parameters. 
(Switching between 100 VAC single-phase and 3-/single-phase is impossible since they have different 
hardware.    A 100 VAC motor is also necessary.) 
 
• High response...

Differences Between PY2 Amplifier and Sanyo Denki’s Conventional Models and 
Precautions 
•  No fuse is built into the main power supply input section. 
On our conventional PY, PZ, PE and PU models, fuses are built into the main power supply input 
sections to save wiring and other reasons when a single axis is used.    On the PY2 amplifier, however, 
no fuse is built in since use of multiple axes is assumed and downsizing is the main theme of its...

•  Sensor cable wiring 
While the maximum length of the sensor cable wiring is 50 m for our conventional PY, PZ, and PE 
models when a standard cable is used, the length is 30 m for the PY2 amplifier for sensor power 
supply reasons (the maximum length is 25 m for the absolute encoder (ABS-E) type). 
The permissible wiring distance can be extended to 50 m by using a cable with low conductor 
resistance (a thick cable) or by increasing the number...
