Boost
Input
If the input optocoupler is energized the MSX changes Boost current. The power stage
increases the run and stop current by 30%.
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 energized, the run and stop current will always be 30%
higher. The Boost function can permanently be switched on by the BOOST DIP switch.
Also see appendix A2.
8.6
Activation
Input
If the input isn’t activated (optocoupler isn’t 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 input Activation 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:
The Activation input can only be used, if the ACTIVATION DIP switch is switched off
(OFF). When the J1 jumper on the board is plugged in position Reset, the Activation input
can only be activated via pin 30a.
See chap. 1.2 and 1.6.
8.7
Reset
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 30c.
See chap. 1.2 and figure 14.
