2.0 Signals input and output
The figure below shows the view of the converter terminals.
M1 Signal terminal 10 pins „type GMST 2,5/10-G-5,08“
M2 Signal terminal 5 pins „type MC 1,5/5-ST-3,81“
POWER Terminals 4 pins „type GMST 2,5/4-G-5,08“
On the test point „TEST“ you can see the signal of velocity speed. The output from 0 to + /-8V
is from zero to maximum speed. At this point you can analyze the signal when you enable one
of the following velocity feedback.
• Encoder
• Armature
• Tachogenerator
Power connector
NOTE: See also the connection diagrams in Chapters 4.1 - 4.2 - 4.3
Signal inputs and outputs
POWER
+HV (IN)
GND (IN)
+MOTOR (OUT)
-MOTOR (OUT) Positive Power supply input
Negative Power Supply input (GND)
Motor connection phase +M
Motor connection phase -M
M1 CONNECTOR
1 FAULT (OUT)
2 REQ
3 GND
4 +9.8V (OUT)
5 –9.8V (OUT)
6 START (IN)
7 +VEL (IN)
8 -VEL (IN)
9 +TACH (IN)
10 -TACH (IN)
Fault drive, open collector output max. 50mA
Normally closed, opens when the drive in protection mode
REQ: can be used in 2 distinct modes:
1) Motor Current limit mode (by REQ setting):
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 REQ (pin 2) and GND (pin 3) terminals. A 47Kohm
external resistor reduces the current by 50%. (Note: The drive velocity loop remains active)
2) Torque request (by REQ setting):
Range: +/- 10V, which corresponds to the drives peak current output. In this mode the velocity loop
is automatically disabled.
Signal Common Ground / Corrisponds to power supply‘s negative GND input
Power 9.8Vdc max 4mA
Power supply –9.8Vdc max 4mA
Positive drive enable with range >+9Vdc min. to +30Vdc max
Reference Positive differential input (Velocity command)
Reference Negative differential input (Velocity command)
PoDT tachogenerator input. This signals corrisponds to power supply‘s negative GND input.
Negative -DT tachogenerator input.
M2 CONNECTOR
+V (OUT)
ENC A (IN)
ENC B (IN)
+L.SW (IN)
- L.SW (IN)
Power 5V max. 130mA
Encoder input Channel A (High logic level from >2,8V to +24Vdc max. Low logic level <1,5V)
Encoder input Channel B (High logic level from >2,8V to +24Vdc max. Low logic level <1,5V)
Clockwise (CW) limit Switch input. (High logic level from >5V to +24Vdc max). To enable this
function, you must open the internal soldiering point SG and SH. See chapter 2.10
Counter-Clockwise (CCW) limit Switch input. (High logic level from >5V to +24Vdc max). To
enable this function, you must open the internal soldiering point SG and SH. See chapter 2.10
