3.4 Putting into Service
• Check the output voltage of the supply unit before plugging in the MSX unit.
• Never plug or unplug the unit when powered.
• Excessive heating of the motor is probably caused by setting too high motor current.
High motor temperature could also be caused by permanent activation of the Boost
function.
• If the motor stops during acceleration, reduce the acceleration and/or the maximum
frequency at the control pulse input. Motor stop may also occur if the nominal motor
current is set incorrectly.
• In case of strong motor resonance, various measures can be taken:
– Select a higher step resolution
– Change the run frequency
– Change the acceleration frequency
– Reduce the motor current
Resonance effects occur more often in the full step mode.
• If the positioning of the motor is incorrect, this may be caused by perturbations on the
pulse input, or by excessive acceleration or motor run frequencies. If the deceleration
is too high, the motor risks mispositioning by multiples of 4 steps (desynchronisation).
• If the supply unit is equipped with a regulation transformer, the voltage of which
increases slowly, a ‘supply voltage’ error can appear. The same error may appear
when using a regulated supply unit with current limitation.
• If several red LEDs shine red after power on or if the green LED ‚Basic position‘ does
not shine, the unit is probably out of order.
• Make always sure before disconnecting that all LEDs don‘t shine. The LED
‚Supply failure‘ must shine for a short time after power-down.
