Parameter Description
high-speed pulse. And the actual delay time is P.157*2ms. For example, if P.157=100, the
actual delay time is 200ms.
5.51 External Terminal Power Enable Function (P.158)
P.158 “External terminal power enable”
Parameter Factory default value Setting range
158 0 0~1
• If P.158=1, select power enables on the external terminals. In this situation, if the functions
of the multi-function control terminals before turning on the power are STF, STR, RUN and
MPO, and the corresponded external terminals are short circuit, and then the inverter will
not run immediately after turning on the power. The inverter will run only after short circuit
these terminals again. When P.158=0, make these terminal short circuit before turning on
the power, and the inverter will run immediately after the power is turned on.
5.52 Energy-Saving Control Function (P.159)
P.159 “Energy-saving control function”
Parameter Factory setting Setting range Remarks
159 0
0 Normal running mode
1 Energy-saving running mode
• Under the energy-saving running mode, the inverter will control the output voltage
automatically in order to reduce the output power losses to the minimum when the inverter
is run at a constant speed.
Note: 1. After selecting the energy-saving running mode, the deceleration time may be longer than the
setting value. In addition, the properties of the regular torque load will produce abnormal voltage
more easily. Please slightly prolong the deceleration time.
2. In the energy-saving running mode, only the V/F control mode is available. That is, only P.300
=0 is
valid.
3. For big load purposes or machines with frequent acceleration/deceleration, the energy-saving
