38 VIX AE SERVO DRIVE USER GUIDE
Motor Overtemperature Sensor
The motor overtemperature switch input is compatible with thermal switches used in Parker
SMB, SME, SM and BE servo motors. The input requires a normally closed switch to be
connected to GND on X2 pin 3 or 6.
If you use a motor with no overtemperature sensor fitted or one with an incompatible
thermistor sensor, make sure you un-check the ‘Thermal sensor fitted’ check box in Custom
Motor Set Up, to prevent an overtemperature fault being reported.
X3 Connector
X3 is the RS232 communications connector. RJ45 connectors X6 and X7 may also be used
for inter-drive communications where multi-axis systems are used.
RS485 Operation
RS485 operation is only possible on drives fitted with the appropriate FEM (Fieldbus
Expansion Module). If you require this feature please order the ViX-CE drive type. RS485
cannot be used simultaneously with RS232.
Connector Type
Connector type is a 9-way D-type socket.

Baud Rate
Use system variable BR to alter the baud rate of serial communications. Any change made
to the baud rate will only take effect following a save (SV) and system reset (Z) or power
cycle.
