Res. Description
1 Set the upper current level as a percentage of
motor rated current. When set to 300%, this
feature is disabled.
1 Set the upper current limit as a percentage of
motor rated current for Acceleration.
1 Set the lower current level as a percentage of
motor rated current for running condition.
1 This is reference for timed overload
characteristic. The inverse time characteristics
will change with change in B305.
This overload setting for Heavy Duty.
This overload setting for Normal Duty.
1 This parameter sets the earth fault detection
level.
1 When enabled, it will prevent the overvoltage
during RUN condition.
=1: Disable
=2: Frequency Increase
=3: Stop Deceleration
1 Set this to prevent unintentional reverse
direction operation. When enabled, ensure that
forward direction is selected in A305 (or at
terminal). The AC DRIVE will not start
otherwise.
=0: Disable
=1: Enable
1 User can change the 4-digit user password for
parameter lock.
1 User selectable 4-digit password to prevent
unintentional parameter changes from the digital
operation panel.
1 The current active parameters will be saved to
non-volatile memory.
The saved parameters will be fetched from
memory and now the drive will respond to these
parameters.
All default values will be loaded excluding C205
to C218 and B202 to B211 as per 60Hz/460V
(US standard).
All default values will be loaded excluding C205
to C218 and B202 to B211 as per 50Hz/415V.
When set to 555, the fault history buffer is
cleared. No previous fault codes and related
parameters will be available.
All the user parameters will be set to default
including C205 to C218 and B202 to B211 as
per 50Hz/415V.
All the PLC parameters will be set to default.
1 For the self-cooling type motor, when operating
at low speed, set these parameters to meet the
motor characteristics.
