07-Start/Stop Command Parameters
Momentary power loss and restart
【0】: Momentary Power Loss and Restart disable
【1】: Momentary power loss and restart enable
If the input power supply suddenly decreases resulting in the DC bus voltage to drop below the under voltage
level, the inverter output is turned off.
When 07-00 =【0】: On power loss, the inverter will not start.
When 07-00 =【1】: Inverter resumes operation after a momentary power loss while running, independent of
the number of restarts.
On power loss, as long as the inverter CPU still has power, momentary power loss restart is enabled based
on the setting of parameters 00-02 and 07-04 and status of external run command.
Caution: After any power loss if the Run mode is set to external run command parameter 00-02=1 and if direct
start on power up is enabled parameter 07-04=0 the inverter will automatically start when power is re-applied.
To ensure safety of operators and to avoid any damages to the machinery, all necessary safety measure must be
considered, including disconnecting power to the inverter.
Number of Auto Restart Attempts
07-02 =【0】: The inverter will not auto restart after trips due to fault.
07-02 >【0】, 07-01 =【0】.After a trip due to fault the inverter will run at the same frequency as before power
loss, and automatically restarts after an internal delay of 0.5 seconds.
07-02 >【0】, 07-01 >【0】, After a fault trip the inverter will run with at the same frequency as before power
loss, and restart after a delay set in parameter 07-01.
Note: Auto restart after a fault does not work while in DC injection braking or decelerating to a stop.
【0】:Enable Reset Only when Run Command is Off
【1】:Enable Reset when Run Command is On or Off
07-03=0 Inverter can only be reset when no run command is present.
07-03=1 Inverter can always be reset when a fault is active.
Caution: When parameter 07-03 is set to 1 the inverter will automatically start after a fault reset and run
command is present (Run mode is set to external run command parameter 00-02=1).
Direct Running on Power Up
【0】:Enable Direct running after power up
【1】:Disable Direct running after power up
When direct run on power up is active 07-04=0 and the inverter is set to external run (00-02/00-03=1), the
inverter will automatically start after power is re-applied. It is recommend to turn off the power switch and run
command switch to avoid injury to operators and damage to machinery when power is re-applied.
Note: If this mode is active all safety measures must be taken including warning labels.
When direct run on power up is disabled 07-04=1 and the inverter is set to external run by (00-02/00-03=1),
the inverter will not auto start when the power is re-applied and the run switch is turned ON. The display will
flash with STP1. It will be necessary to cycle the run command switch to start the inverter.
