36 Unidrive SP Short Form Guide
www.controltechniques.com Issue Number: 2
*Marker pulse is optional.
**Simulated encoder output only available in open-loop.
***The encoder supply is selectable through parameter configuration to 5Vdc, 8Vdc and
15Vdc.
****Terminal 15 is a parallel connection to T8 analog input 3. If this is to be used as a
thermistor input, set Pr 7.15 to ‘th.sc’ (7), ‘th’ (8) or ‘th.diSP’ (9).
4.6 Serial communications connections
The Unidrive SP has a serial communications port (serial port) as standard supporting 2
wire EIA485 communications.
Table 4-2 Connection details for RJ45 connector
The communications port applies a 2 unit load to the communications network.
Minimum number of connections are 2, 3, 7 and shield. Shielded cable must be used at
all times.
