Power Supply Function
this protection limit and the delay time is exceeded, the power supply will enter
the OCP state.
Possible Cause
Many reasons can cause OCP, the details are as follows:
• The set protection limit Level is lower than the current Meter value.
• The external (AC input) inputs a higher current.
• The power supply outputs a high current due to a fault.
How to Set
The operation steps to set OCP are as follows.
1. Press the composite keys [Shift]+[Recall] (Protect) on the front panel to en-
ter the protection menu.
2. Press the up/down key or rotate the knob to select 2. OCP (Off) and press
[Enter].
3. Press the left/right key or rotate the knob to select On and press [Enter] to
enter the setting interface.
4. Set the protection limit Level and the delay time Delay in sequence, and
press [Enter] to confirm.
The VFD screen returns to the Protect menu and the OCP setting (take 10A,
1S as an example) is displayed as follows:
PROTECT
2.OCP 10A, 1.000S
4.5.3 Set Over-Power Protection (OPP)
Users can enable the OPP function and set the protection limit Level and pro-
tection delay time Delay. When the power (i.e., the Meter value) is greater than
this protection limit and the delay time is exceeded, the power supply will enter
the OPP state.
Possible Cause
Many reasons can cause OPP, the details are as follows:
• The set protection limit Level is lower than the power Meter value.
• The power supply outputs a high power due to a fault.
