Signal inputs and outputs
1.9
M1 CONNECTOR
1 CURR (OUT)
Current motor monitor: +/-4Vdc=Rated current, +/-8Vdc=Peak
current output in Volts. This output may be used to monitor the
torque the motor is producing.
2 OK (OUT)
Drive OK, open collector output max. 50mA
(Normally closed, opens when in protection mode)
3 TPRC (IN)
This signal can be used in 2 distinct modes
1) Motor Current limit mode:
A motor current limit mode connect an external resistor to
GND reduces the maximun current. Connect a 1/4W o 1/8W
resistor between the TPRC (pin 3) and GND (pin 4)
terminals. A 47Kohm external resistor reduces the current by
50%. (Note: The drive velocity loop remains active)
2) Current Reference (Torque Input)
Range: +/- 10V, which corresponds to the drives peak current
output. In this mode the velocity loop is automatically
disabled.
4 GND
Signal Common Ground
Corrisponds to power supply's negative GND input
5 +10V (OUT)
Power 10Vdc max 4mA
6 -10V (OUT)
Power supply -10Vdc max 4mA
7 ENABLE (IN)
Positive drive Enable with range >+8Vdc min. to +30Vdc max. It's
also possible to enable the drive with negative logic by
connecting a GND input, see chapter 2.10
8 +VEL (IN)
Reference Positive differential input (Velocity command)
9 -VEL (IN)
Reference Negative differential input (Velocity command)
10 CHA (IN)
Encoder input Channel A (High logic level from >2,8V to +24Vdc
max. Low logic level <1,5V)
11 CHB (IN)
Encoder input Channel B (High logic level from >2,8V to +24Vdc
max. Low logic level <1,5V)
12 +5V (OUT)
Power 5V max. 130mA
13 GND
Signal Common Ground. Corrisponds to power supply's negative
GND input.
14 HU (IN)
15 HV (IN)
16 HW (IN)
Hall Sensor inputs from the motor. Each input has a pull-up
resistor of 1 Kohm to internal +5V (High logic level >3,2V , Low
logic level <1,5V)
