NO.6 Detailed Function Description

6.2 Application function parameters

P023
Reverse prohibit
0: Reverse prohibit
This parameter setting is applied to sites where motor is irreversible so as to avoid
misoperation of operators. When reverse is prohibited, motor can only rotate in a forward
way rather than in a reverse way.
P024
Is stop key valid?
0: STOP key is invalid
When control mode refers to external terminal control or communication control, the stop key
on the panel can select whether to be valid. If selecting valid, the panel will stop the inverter.
If it is necessary to restart, remove the running signal firstly and then restart the inverter.
This parameter is only valid when P001 is set as 1 or 2.
P025
Startup mode
Two kinds of startup modes can be set as required by different equipment.
0: Start from startup frequency. When P029 is set as zero, the DC braking at the time of
startup is invalid and the startup shall be conducted from start-up frequency. When P029 is
not zero, the DC braking at the time of startup is valid; when starting, firstly start the DC
braking and then start from start-up frequency.
1: Frequency tracking startup: this parameter can be used to restart of high-inertia load.
When restarting, operating command can be executed without fully stopping of equipment
and tracking startup also can be made to save time. Refer to Figure 6-3 for details.
Refer to P027,P029 and 031P for relevant parameters.
[Note] During frequency tracking startup, the frequency set by inverter will make
