Support

Features:
1. Support EtherCAT distributed IO, and maximum up to 32,000 points;
2. Excellent motion control function including interpolation, chasing cut, flying cut and so on;
3. Visualization configuration, support IL, LAD, FBD, SFC, ST, CFC 6 programming language;
4. Abundant field bus including EtherCAT, CANopen, Ethernet and modbus;

The main difference between AX70 and AX71:
AX70 can support 32 axes via EtherCAT communication, and AX71 can only support 8 axes.

'R': relay output; 'T': transistor output(NPN); Please note that INVT PLC doesn't support PNP output.

Adjust V/f control parameters properly.
1. Slip compensation P04.09
2. Suppression of oscillation P04.10, P04.11, P04.12, P11.27 (VF oscillation suppression method selection, ones bit effective)
3. PWM selects the ones bit in P08.40

According to customer needs, models with 500V and 660V voltage levels can be provided.

Usually a HMI with special air compressor program is needed. The HMI operation is intuitive and simple, and the air compressor can be debugged without instructions. In addition, in order to meet the operating habits of different customers, an LCD keyboard can also be selected to realize all parameter settings and debugging of the integrated machine.

Hibernation is a function for saving energy, when the pressure/flow requirement is very little for a long time, VFD enter to hibernation status. There are 2 kinds of hibernation, according to the running frequency or deviation, the hibernation internal logic is as attachment.

Possible causes of failure:
1. The short-circuit connection jumper between terminal 24 V and PW is lost;
2. The voltage of terminal 24 V is abnormal;
3. The terminal is damaged;
4. The terminal polarity is set incorrectly;
5. Some parameter setting is improper, please reset to factory parameters, then test.

Inspection running can be used to check whether the lift is running properly.

During inspection running, check whether the actual lift running direction is the same as the direction in the command. If not, exchange any two cables of U, V, and W or set P00.06=1.

Note: For the synchronous motor, changing the motor cables requires autotuning the motor parameter (pole angle) again. It is recommended to set P00.06 to change the lift running direction.

GD350 needs to be equipped with a Bluetooth card, scan the QR code on the inverter, download and install INVT Workshop, and open the mobile phone Bluetooth to connect to the inverter. See the video link below for more steps.
