2. Installation process

2.1 Installation Preparation

Environmental requirements: temperature 0-40 ℃ (with a 2.5% reduction in capacity for every 1 ℃ increase in temperature between 40-50 ℃), relative humidity<90% (non condensing), altitude ≤ 1000m (with a 1.1% reduction in capacity for every 100m exceeding 1000m).

Hardware requirements:

Equipment/tool specification requirements

Minimum PC: Pentium III 500MHz, 128MB RAM, 50MB hard disk space; Recommendation: Above 1GHz, 1GB RAM

Cable motor power line (shielded twisted pair, up to 30.5m), feedback cable (shielded twisted pair, 22AWG or above)

Tools: Small screwdrivers below 3mm, M5 bolts, crimping tools

Other regenerative resistors (7.5A and above models require external installation), EMC filters (required for CE compliance)

2.2 Key Connection Steps

Mechanical installation: Vertically fixed on a non flammable surface, leaving 50mm of heat dissipation space at the top/bottom, and installed side by side with a spacing of ≥ 13mm.

Electrical connection:

Power connection: Single corresponding L/N terminals, three-phase corresponding L1/L2/L3 terminals, must be reliably grounded.

Motor connection: The U/V/W terminals correspond to the motor winding, and it is necessary to distinguish the cable pin configuration of rotary/linear motors.

Feedback connection: resolver (9-pin D-type interface), encoder (15 pin D-type interface), signal pair requires twisted pair, shielding layer single ended grounding.

Regenerative resistor: Connect R1/R2 terminals, keep away from flammable materials, and leave enough space for heat dissipation.

3. Operation and Configuration

3.1 Software Operation

Software installation: Install Mint WorkBench via CD-ROM, supporting Windows 2000/XP/Vista systems.

Debugging process:

Connect the PC to the driver (RS232 is preferred, recommended for first-time installation).

Start the Commissioning Wizard to complete the motor parameter configuration and automatic tuning.

Perform test movement: Start the motor with the command JOG. 0=10, stop with STOP. 0, and monitor the Spy window parameters.

3.2 Core Function Configuration

Control mode:

Current control: Receive torque reference signal and adjust motor current through PI controller.

Speed control: Tracking speed reference through PID controller, supporting acceleration/deceleration configuration.

Position control: Supports pulse and direction input, preset movement, point-to-point movement (exclusive to Flex+DriveII).

Preset Mobile and PLC Tasks:

Preset movement: Up to 256 sets can be stored (CAN extension required), which can be triggered through digital input or software.

PLC task: supports condition judgment and action execution (such as limit triggered shutdown), and can save configuration files (in. plc format).

4. Troubleshooting and Safety Standards

4.1 Common fault handling

Troubleshooting direction

Check the connection between the 24VDC control power supply and the AC main power supply when the status display is blank

Communication failure confirmation RS232/RS485 switch (SW1-10), cable wiring, COM port conflict

Unstable motor, re tuning current loop, reducing speed loop gain (KVPROP/KVINT)

Overvoltage fault check input voltage, increase regeneration resistance, and reduce deceleration rate

4.2 Safety Regulations

It must be operated by professionals. Before operation, disconnect the high-voltage power supply and confirm reliable grounding.

The wiring must comply with NEC/CE standards, with separate wiring for power and control lines, intersecting at a 90 degree angle.

Regenerated resistors may generate high temperatures, keep away from flammable materials; Even if the motor circuit is shut down, there may still be high voltage present.
