11.1.5 Input
If current flows through the optocoupler, the MSX
+
increases the run and stop current for
by the value programmed in the ServiceBus.
Thus, a higher torque can be reached during the acceleration and deceleration time of the
motor by changing to Boost current.
As long as the Boost input is energised, the run and stop current will always be higher.
Also, see chap 11.1.5
11.1.6 Input
If the input is not activated (optocoupler not energized), the motor current is switched off.
This input (pin 30ac) is useful, for instance, during maintenance operations to switch the
power stage off, without having to disconnect it physically from the mains. It is possible
now to rotate the motor by hand slowly.
WARNING!
The Activation input is not in conformance with the professional emergency
stop circuit requirements!
The Activation input may also be used to avoid the inevitable electrical noise emissions of
the power stage, e.g. if you have to perform sensitive electrical measurements in the
environment of the device.
Important:
When the J1 jumper on the board is plugged in position Reset, the Activation input can
only be activated via pin 45e. See chap. 8.4. and 11.1.7.
11.1.7 Input
The Reset input only is available, when J1 jumper is plugged in position Reset on the
board. Reset can be activated by the pin 45a.
See chap. 8.4 and figure 14 next page.
