External +24V Provide +24 V power supply to external unit. Generally, it provides
+24V-COM power Supply power supply to DI/DO terminals and external sensors.
Maximum output current: 200 mA
Input terminal of Connect to +24 V by default. When DI1-DI5 need to be driven by
OP external power external signal, OP needs to be connected to external power
supply supply and be disconnected from +24 V.

If PP-00 is set to a non-zero number, parameter protection is enabled. You must enter the correct user
password to enter the menu.To cancel the password protection function, enter with password and set
PP-00 to 0.Group F and Group A are standard function parameters. Group U includes the monitoring
function parameters.The symbols in the function code table are described as follows:
"☆": The parameter can be modified when the AC drive is in either stop or running state.
"★": The parameter cannot be modified when the AC drive is in the running state.
"●": The parameter is the actually measured value and cannot be modified.
"*": The parameter is factory parameter and can be set only by the manufacturer.

Faults and Solutions The MH300 provides a total of 24 pieces of fault information and protective
functions. After a fault occurs, the AC drive implements the protection function, and displays the fault code on
the operation panel (if the operation panel is available). Before contacting Manufacture for technical support,
you can first determine the fault type,analyze the causes, and perform troubleshooting according to the
following tables. If the fault cannot be rectified, contact the agent or Manufacture. Err22 is the AC drive
hardware over-current or over-voltage signal. In most situations, hardware over-voltage fault causes Err22.
Solutions to the faults of the MH300.
