Commissioning
5.5 First commissioning with the AOP30
Note
Pre-defined encoder type
If a predefined encoder type is selected using p0400, then the settings of the following
parameters p0404, p0405 and p0408 cannot be changed.
If the connected encoder does not match any of the encoders predefined in p0400, follow the
simple procedure below for entering the encoder data:
• Via p0400, select an encoder type whose data is similar to that of the connected encoder.
• Select "User-defined encoder" (p0400 = 9999). Previously set values are stored here.
• Adjust the bit fields of p0404, p0405, and p0408 to the data for the connected encoder.

NOTICE
Material damage when selecting the incorrect encoder supply voltage
Once the encoder has been commissioned, the supply voltage (5/24 V) set for the encoder
is activated on the SMC30 module. The encoder may be damaged, if a 5 V encoder is
connected and the supply voltage has not been set correctly (bit 20 = "Yes," bit 21 = "No").
• Set the correct supply voltage for the connected encoder.
