16 BD SERVO DRIVES USER GUIDE
Motor Feedback Pin Description
The user motor feedback connector is a 25-way D-type which carries motor monitoring signals.
Connection to the User I/O connector must be made using a metal cased backshell D-type
connector and the securing screws must be fully tightened before use.
Pin 2 & 15 0V
0V return for +5V supply.
Pin 3 & 16 +5V
+5V current limited supply (200mA maximum). Take care to minimise any voltage drop when
using cables longer than 10 metres.
Pin 4 Tach 0V
Tach input 0V return.
Pin 5 Tach Input
Tach input. The Tach input pins are not normally used. They are reserved for use with a
brushed tachometer for high performance applications.
Pin6 0V
0V return for thermistor.
Pin 7 Thermistor
For thermal protection of the motor, a normally closed thermal switch or a PTC thermistor
mounted in the motor is connected between pins 6 and 7. The thermistor should have a
transition resistance between 100R and 10k
Ω
.
Pins 8 to 13 Inc Encoder Inputs
The incremental encoder inputs are connected to a 26LS32 line receiver. The set up of the
encoder is described in
Appendix A.
Pins 20 to 25 Comm Encoder Inputs
The commutation encoder inputs are described in the section describing bit switch 3 settings and
Appendix A.
