Assembly and Commissioning Instructions Servo amplifier D1-N  15.10.2015 
 
Testing the wiring for the STO safety function 
•  Apply 24 VDC voltage at SF1 and SF2 and energise the motor via input 1 at 
X6. -> Motor is energised. 
•  Deactivate SF1 -> D1-N delivers error message “E18 STO activated” and 
motor is de-energised. 
•  Reactivate SF1 and establish connection between DSF+ and DSF- at X6 for 
1 second. -> Motor is energised. 
•  Deactivate SF2 -> D1-N delivers error message “E18 STO activated” and 
motor is de-energised. 
•  Reactivate SF2 and establish connection between DSF+ and DSF- at X6 for 
1 second. -> Motor is energised. 
•  Deactivate SF1 and SF2 at the same time -> D1-N delivers error message 
“E06 motor may be disconnected” and motor is de-energised. 
•  Reactivate SF1 and SF2 and establish connection between DSF+ and DSF- 
at X6 for 1 second. -> Motor is energised. 
 
•  To test the function of the safety inputs SF1 and SF2 with 24 VDC, the fol-
lowing power supply can be used: 
   
   
   
   
   
If disabling the safety inputs is not leading to the desired function (motor 
disable) or the restart of the device with DSF+ and DSF- fails, please con-
tact the HIWIN support (See section 2.9 on page 14).
