Chapter 1 Inspection and safety precautions 1-1.Contents of this chapter This chapter mainly describes the precautions related to product handling, installation, operation, maintenance, disassembly and waste disposal. Safe operation depends on proper transportation, installation, operation, and maintenance. Failure to pay attention may result in system damage, personal injury, or even personal injury.
Page 9 Chapter 1.Inspection and safety precautions Type Explanation related operations. The waiting timetable is as follows, for reference, subject to the actual situation:： Inverter model At least wait time Voltage level 380V 0.75G-110G 5 minute Voltage level 380V 132G-315G 15 minute Voltage level 380V more than 315G 25 minute...

●Determine whether the communication mode required by the inverter requires an external communication card. ●Do not change the three-phase inverter in the PI550 series to two-phase use, otherwise, the inverter will be damaged. ●The cooling fan of the ordinary three-phase asynchronous motor is coaxially connected to the rotor shaft, and the cooling effect of the fan is reduced when the speed is reduced.
Page 12 Chapter 2.Quick Installation Guide ●When the ambient temperature exceeds 40°C, please derate by 10% at 1°C. Please do not use the inverter in an environment above 50°C. ●In order to improve the reliability of the machine, use the inverter in a place where the temperature does not change rapidly.

Chapter 2.Quick Installation Guide inverter, it is not allowed to use this contactor to control the start and stop of the inverter. The contactor must be used to control the start and stop of the inverter, and the interval should not be less than one hour. Frequent charging and discharging will easily reduce the service life of the capacitors in the inverter.
Page 15 Chapter 2.Quick Installation Guide ●Adjust the acceleration and deceleration time according to the actual working conditions of the load. If there is no special requirement for the acceleration and deceleration time, the acceleration and deceleration time can be lengthened appropriately to reduce the current impact of the inverter. ●Jog the device to make sure that the motor direction is the same as the required direction.

Read and write function code parameters (some function codes cannot be changed, and are only used by manufacturers or monitored): Function code parameter address marking rules: The rules are represented by the function code group number and label as the parameter address:...

If it is a parameter of group E, to realize this function, just change the high-order A of the function code address to 4 and it can be realized.

Communication Notes: 1: First of all, the communication protocol settings of the master and slave should be consistent: baud rate, data format, slave address, communication protocol, etc. 2: The communication parameter address conversion should be correct, and the slave address conversion should pay attention to whether it is in decimal or hexadecimal.
