HD2 Series Inverter Function Parameter List
-211-
threshold of
phase-lock loop
switch-in
threshold for enabling the counter-electromotive
force phase-locked loop in SVC 0. When the
running frequency is lower than the value of this
parameter, the phase-locked loop is disabled; and
when the running frequency is higher than that, the
phase-locked loop is enabled.
Setting range: 0.00–655.35
Maladjustment
detection time
This parameter is used to adjust the
responsiveness of anti-maladjustment function. If
the load inertia is large, increase the value of this
parameter properly, however, the responsiveness
may slow down accordingly.
Setting range: 0.0–10.0s
High-frequency
compensation
coefficient of
synchronous
motor
This parameter is valid when the motor speed
exceeds the rated speed. If motor oscillation
occurred, adjust this parameter properly.
Setting range: 0.0–100.0%
High-frequency
injection current
0–300.0% (of the rated inverter output current)
P14––Serial communication function
Local
communication
address
Setting range: 1–247
When the master is writing frames, and the slave
communication address is set to 0, it is the
broadcast communication address, and all the
slaves on the Modbus bus will accept this frame,
but the slave never responds.
Local communication address is unique in the
communication network, which is the basis for
point-to-point communication between the upper
computer and the inverter.
Note: The slave address cannot be set to 0.
Communication
baud rate setup
This parameter is used to set the data
transmission speed between upper computer and
