• When parameters are set the value is automatically stored
in the internal memory.
• When r000 is selected (and P005=21), the display shows the
the actual frequency or when the drive is stopped, the
display flashes every 1.5 seconds the frequency setpoint..
• The speed of the drum can be changed on the fly when you
use the UP or DOWN buttons to change the output frequency
in r000.
• If the acceleration or deceleration of the frequency is too
fast the MicroMaster goes into a protective mode for a
while and then continues. The output frequency is reduced
until the current falls below its limit.
During this process the display flashes as warning.
Increase the time for acceleration or deceleration to avoid
this phenomenon.
• Parameter 964 shows the software version
• In the event of a failure the converter switches off and an
error code appears in the display. The last recorded error
is stored in parameter number 947[8].
