Note 1.    Set alarm output sequence at Func2 Bit6 of Mode2-Page3. 
        When Func2 Bit6 = “0”, CODE is displayed, and when Func2 Bit6 = “1”, BIT is displayed. 
Note 2.    “0” and “1” in the alarm output are: 
        “0” = Output is short-circuit, “1” = Output is open, when Mode2 Page3 Func2 Bit7 = “0”   
        “0” = Output is open, “1” = Output is short-circuit, when Mode2 Page3 Func2 Bit7 = “1”. 
 
 
3.  Precautions 
1)  This function only outputs warning, and does not execute sequence process such as Servo OFF in 
the alarm output or dynamic brake stop.    In case of overload warning output, prevent overload alarm 
by reviewing the system operation cycle etc. 
2)  Warning output recovers automatically when the estimated motor temperature becomes lower than 
the set value for warning output (Overload alarm is not canceled without alarm reset procedure).   
Even in SOFF status, warning is output if the estimated motor temperature is higher than the set 
value.   
3)  When this function is validated, estimated motor temperature becomes Cold Start (Estimated motor 
temperature is 0% of the overload alarm level when the control power is turned on).    Do not restart 
the system immediately after the power turn ON and OFF due to overload alarm, since the motor may 
not be cool enough.    Otherwise, it may lead to burnt or damage of the motor or an accident.
  
Secure enough time before restarting the system. 
4)  When overload warning and overtravel warning occur simultaneously, overtravel warning is prioritized 
in the 7-segment LED display.

10.1.1 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, make sure to use them in a pollution level 1 or 2 environment. 
 
 
 
10.1.2 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.

 10.2 CE Marking 
At Sanyo Denki, we are executing tests on the PY2 Servo Amplifier for compliance with the CE marking 
at qualifying institutions.    The CE mark is required to be attached all end products sold in EU countries.   
Only products conforming to the safety standards are permitted to have them.  Accordingly, customers 
are requested to perform the final conformity test on their machines or systems incorporating our 
amplifiers.

10.2.3  Structure of the Control Panel 
1.  A metallic material is used for the control panel and its cover. 
2.  The joint of the roof and the side board shall be masked and welded. 
3.  The joint fixed with screws shall be welded to prevent noise from leaking from the gap in the joint. 
4.  In case of fixing with screws or spot welding, the welding space shall be within 10 cm. 
5.  Use an EMI gasket to prevent clearance between the cover and the control panel. 
6.  The EMI gasket shall be installed uniformly on the joint section of the cover and the control panel.
