Issue Number: 2
Pr 00.022 determines whether the reference is uni-polar or bi-polar as
follows:
Open-loop
If the preset reference has been selected (see Pr 00.005), the speed at
which the motor runs is determined by these parameters.
RFC-A / RFC-S
If the speed feedback (Pr 03.002) exceeds this level in either direction,
an overspeed trip is produced. If this parameter is set to zero, the
overspeed threshold is automatically set to 120 % x
SPEED_FREQ_MAX.
Open-loop
Refer to Pr 00.024 to Pr 00.026.
This parameter shows the number of the data block last transferred from
a SMARTCARD to the drive.
* Only a value of 3 or 4 in this parameter is saved.
If Pr 00.030 is equal to 1 or 2, this value is not transferred to the
EEPROM or the drive. If Pr 00.030 is set to a 3 or 4 the value is
transferred.
