+ : Set this parameter to 3 if you want to change parameters > 9. If the
machine is shipped to the customer set this parameter to value indicated in the
list.
! : Autocalibration of the stator resistance has to be done only once after
connecting the motor to the converter. This value is then stored in parameter
89.
Warning:
The value of parameter 89 should be around 8 ohms. If this not the case, set
this value to 8.
! : Autocalibration of the stator resistance has to be done only once after
connecting the motor to the converter. This value is then stored in parameter
89.
Remark:
• When parameters are set the value is automatically stored in internal memory.
• When P000 is selected (and P001=0), the actual frequency is displayed or when
the drive is stopped, the display flashes the frequency setpoint every 1.5 seconds.
• Do not change P051 to alter the rotation. SWAP 2 wires when needed.
• The speed of the drum can be changed when you use the UP or DOWN buttons to
change the output frequency in P000.
• If the acceleration or deceleration of the frequency is too fast the Micro Master
goes into a protective mode for a short time 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.
• If P944 is set to 1 then the parameters are set to factory defaults. So be careful !!
• If P910 is set to 1 then access to parameters becomes remote (through RS485).
• Parameter 922 is the software version.
