Interfaces
Inputs
All inputs include an optocoupler with series resistors for
5 V or 24 V-supply voltage.
The signals are active, when the optocoupler is energised.
Optocoupler input current is about
10 mA for MSX
+
5 V standard version or
5 mA for MSX
+
24 V version
pulse
Control
Maximum step frequency: 500 kHz
Minimum pulse width: 1
s
The step is executed with the falling flank of the control pulses.
Motor direction
When the optocoupler is energised, the motor rotates in the
reverse direction (as compared to the preferential motor
direction selected).
Boost
When the optocoupler is energised, the MSX
+
increases the
run and stop current by 30%.The Boost function can
permanently be activated by the DIP switch.
Activation
When the optocoupler is energised, the motor current is
activated.
Reset
Is available only, when J1 jumper is plugged in position RESET
on the board. The power stage is set to an initial state. A signal
Basic position is generated for each Reset.
Outputs
Optically insulated from the motor voltage, Type Open-
Collector I
