1.7 Signal inputs and outputs
General Description
Drive OK, Open Collector output 50mA Max. (Normally closed,
opens when in protection mode)
This signal can be used in 3 distinct modes:
A) Motor Current Limit Mode:
Soldering point S8 open S9 closed.
Applying a signal between zero and +10V you receive the
current limitation output from zero to max. drive size.
Ex:
Mcs Plus10/20A.......+5V limits the current to +/-10A.
Mcs Plus 14/28A.....+3.2V limits the current to +/-9A.
Note: The drive velocity loop remains active.
Ving=10 x I required
I peak
B) Motor Current Limit Mode:
S8 closed S9 open.
A motor current Limit mode connect an external resistor to
GND (pin 4) reduces the maximun current. Connect a 1/4W o
1/8W resistor between the TPRC and GND terminals.
A 47Kohm resistor reduces the current by 50%.
Note: The drive velocity loop remains active.
