Note：
Note:
1. Please select the appropriate braking resistor according to the site working conditions and the 《Braking Resistor Specification Parameters》.
2. The multi-function input terminals (X1 to X4/PUL) can support NPN transistor signals as inputs.
3. The analogue monitoring output is a dedicated output for indicator meters such as ammeters and voltmeters, and should not be used for control
operations such as feedback control.
4. As there are several pulse types in practice, please see the detailed description for the specific wiring.
5. For 0.4kW to 5.5kW drives, the COM and GND terminals are two-in-one function terminals and are combined externally as GND terminals; for
7.5kW to 22kW drives, both COM and GND terminals are available.
