X220 TTL encoder

Table 4- 13 Encoder interface X220
Type: Sub-D socket, 15-pin; TTL encoder; max. cable length 100 m
Note
Only 5 V TTL encoders are supported.
Electric shock in the event of voltage flashovers at the temperature sensor
Voltage flashovers to the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
• Use temperature sensors that comply with the specifications relating to safe electrical

supply voltage of the encoder system, and adjusts the supply voltage for the encoder system at the output of the drive
module until the required supply voltage is obtained directly at the encoder system.
