“LOCAL/REMOT”
LED lights on)
The operation of inverter can be controlled by host through communication. If select
“Communication”, the user should select the serial communication extension card which
matches with CHV180 serials inverter.

P0.02 is the rated speed on the elevator nameplate; the setting value should be less
than the elevator rated speed. The relationship of the inverter’s output frequency and
the elevator’s running line speed is linear. The expression is as follow:

Thereinto,
f
represents output frequency of elevator,
v
represents running linear speed
of the elevator,
D
represents diameter of tractor (P2.01),
i
represents reduction
ratio(P2.02),
k
represents hoist hanging ratio(P2.03),
N
f
represents rated
frequency of motor (P2.05),
N
n
represents rated rotational speed of motor (P2.06).
Note: The speed of elevator is limited by P0.02, and the maximum output
frequency of inverter is limited by P0.04, so the maximum running line speed of
elevator is limited by both P0.02 and P0.04.
