Comments:
VREF1+/VREF1-: Analog Input (+/-10Volt) to control the speed reference of motor when the power driver is configured in SPEED MODE or to control the current reference of motor when the power driver is configured in CURRENT MODE.
VREF2+/VREF2-: Analog Input (0(10Volt) to limit the maximum torque of motor (option)
ENABLE: Digital Input (15(24V 20 mA) to manually Enable the Power of driver
SBLOMAN: Digital Input (15(24V 20 mA) to manually Unlock the Brake of motor
FAULT1/FAULT2: relay contacts normally closed when the power driver status is OK.
The contacts are open when the power driver is in Error status

|8 |N.C. |Not connected |
[pic]
Comments: used to connect a PC serial line. The two connector merge exactly same electrically signals, so in RS485 bus you can use X7 as Input connector and X8 as output connector (or viceversa).
RS232: Maximum lenght cable = 10 meters, max capacitance = 2500 pF.
Shielded cable.
RS485: Maximum lenght cable = 100 meters, max capacitance = 100 pF/meter.
Impedance = 120 ohm typ.
