*
Mating half of connector not supplied
15-way D-type (male)
Start, serial enable and remote enable:
Enable control voltage: low (closed) 0 to 0.8 V d.c. (l
OUT
= 0.55 mA nominal)
Disable control voltage: high (open) 4 to 26.4 V d.c. (Internal pull up to 6.4 V nominal)
Standby control input:
Enable control voltage: low (closed) 0 to 0.8 V d.c. (l
OUT
= 0.3 mA nominal)
Disable control voltage: high (open) 4 to 26.4 V d.c. (Internal pull up to 3.2 V nominal)
Analogue and RS485 enable control inputs:
Enable control voltage: low (closed) 0 to 0.8 V d.c. (l
OUT
= 0.55 mA nominal)
Disable control voltage: high (open) 4 to 52.8 V d.c. (Internal pull up to 6.4 V nominal)
Analogue speed input
