4.1.5 Parameters that cannot be changed while running
For reasons of safety, the following parameters have been set up so that they cannot be reprogrammed while
the inverter is running. Stop operation (“” or “QHH” is displayed) before changing parameter settings.
[Basic parameters]
CW (Automatic acceleration/deceleration)
CW (Automatic torque boost)
CW (Automatic function setting)
EOQF(Command mode selection)
HOQF(Frequency setting mode selection 1)
V[R (Default setting)
HJ (Maximum frequency)
XN (Base frequency 1)
XNX (Base frequency voltage1)
RV (V/F control mode selection 1)
[Extended parameters]
H : Priority selection
H∼H : Input terminal selection parameters
H∼H : Output terminal selection parameters
H : Base frequency 2
H : Base frequency voltage 2
H : Jog stopping pattern
H∼H : Protection parameters
H : Carrier frequency control mode selection
H : Braking mode selection
H : Release frequency
H : Creeping frequency
H : Auto-tuning
H∼H : Motor constant parameters
H : Exciting strengthening coefficient
H : Stall cooperation gain at field weakening zone 1
H : Stall cooperation gain at field weakening zone2
H : Motor adjustment factor
H : Emergency stop selection
H : Output phase failure detection mode selection
H : Input phase failure detection mode selection
H : Detection of output short-circuit during start-up selection
H : Over-voltage stall protection level
H : Under voltage trip/alarm selection
H : Logic output/pulse train output selection (OUT-NO)
H : Step-out detection current level (for PM motors)
H : Step-out detection time (for PM motors)
The setting of any parameter other than the above can be changed even during operation.
Keep in mind, however, that when the parameter H (prohibition of change of parameter settings) is set to
(prohibited), no parameters can be set or changed.
Set H, and they can be changed while
the inverter is running.
