TR200 Programming Guide
Function:
Use this parameter along with par.1-51
[RPM] to obtain a different thermal load on the motor when running at
low speed.
Enter a value which is a percentage of the rated magnetizing current. If
the setting is too low, the torque on the motor shaft may be reduced.
Function:
Set the required speed for normal magnetising current. If the speed is
set lower than the motor slip speed, par.1-50
Zero Speed and par.1-51 Min Speed Normal Magnetising [RPM]
no significance.
Use this parameter along with par.1-50
Speed. See drawing for par.1-50
Function:
Set the required frequency for normal magnetising current. If the fre-
quency is set lower than the motor slip frequency, par.1-50
netisation at Zero Speed and par.1-51
[RPM] are inactive.
Use this parameter along with par.1-50
Speed. See drawing for par.1-50
Function:
Enter the % value to compensate voltage in relation to load when the
motor is running at low speed and obtain the optimum U/f characteristic.
The motor size determines the frequency range within which this pa-
rameter is active.
