Parameter Description
Parameter Description
•
Provided that the values of P.24~P.27 and P.142~P.149 are all defaulted, the ‘3-speed operation’ is
active. In this case, the target frequency can be set as follows (the priority for the terminals is RL
RM RH):
Parameter
Target
Frequency
P.24=
9999
P.25=
9999
P.26=
9999
P.27=
9999
P.142=
9999
P.143=
9999
P.144=
9999
P.145=
9999
P.146=
9999
P.147=
9999
P.148=
9999
P.149=
9999
RL
P.6
RM
P.5
RH
P.4
For example: if P.26=9999, the target frequency is determined by RM (the setting value of P.5).
Note: 1. The multi-speed is valid only at the external mode, the combined mode 2, the combined mode 4 or the
combined mode 5.
2. RL, RM, RH and REX mentioned in this section are the function names of the multi-function control
terminal. (For example:
P.80
=2, M0 terminal is chosen to perform the RL function). Please refer to
P.80~P.84, P.86
for multi-function selection, and refer to
Section 3.5.6
for wiring.
5.5 Acceleration/deceleration Time (P.7, P.8, P.20, P.21, P.44, P.45)
P.7 “Acceleration time”
P.8 “Deceleration time”
P.20 “Acceleration/deceleration
reference frequency”
P.21 “Acceleration/deceleration time
increments”
P.44 “Second acceleration time”
P.45 “Second deceleration time”
When the output frequency of the inverter accelerates from 0Hz to P.20, the required time is
defined as acceleration time (P.7).
When the output frequency of the inverter decelerates from P.20 to 0Hz, the required time is
defined as deceleration time (P.8).
P.21 is used to set the acceleration/deceleration time and minimum setting increments.
