Parameter Description
Parameter Description
49
• 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

P.25=

P.145=

P.146=

P.147=

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 “The second acceleration time”
P.45 “The second deceleration time”
● When the output frequency of the inverter accelerates from 0 Hz 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 0 Hz, the required time is
defined as deceleration time (P.8).
● P.21 is used to set the acceleration/deceleration time and minimum setting increments.
