during RUN condition.
=1: Disable
=2: Frequency Increase
=3: Stop Deceleration
B308
Reverse Direction
Lock
0 0 1 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

parameter lock.
B310
Parameter Lock 0 0 9999 1 User selectable 4-digit password to prevent
unintentional parameter changes from the digital
operation panel.
B311
Default Value Load
0 0 111 1 The current active parameters will be saved to
non-volatile memory.
222 The saved parameters will be fetched from
memory and now the drive will respond to these
parameters.
333 All default values will be loaded excluding C205
to C218 and B202 to B211 as per 60Hz/460V
(US standard).
444 All default values will be loaded excluding C205
to C218 and B202 to B211 as per 50Hz/415V.
555 When set to 555, the fault history buffer is
cleared. No previous fault codes and related
parameters will be available.
666 All the user parameters will be set to default
including C205 to C218 and B202 to B211 as
per 50Hz/415V.
777 All the PLC parameters will be set to default.
Note:
The value entered in this parameter will not be memorized. It correct value is entered, appropriate action will be taken
and “00” will be displayed. If incorrect value is entered, no action will be taken and “00” will be displayed.
B312

Setting
% 105 0 B313 1 For the self-cooling type motor, when operating
at low speed, set these parameters to meet the
motor characteristics.
