3.2 Wiring When making power and control connections, the following should be observed: (1) Check that the motor and supply voltage correspond to the values on the rating plate of the soft starter. (2) Connect the incoming AC power wires from the power disconnect and/or protection devices to R, S and T terminals, and tighten each terminal.

4. Operation 4.1 Human-Machine Interface (HMI) The Starter utilizes a HMI that allows the user to operate the starter. It includes an easy- to-read display and keypad to scroll through the parameters. The HMI allows the user to control the starter (run, stop, and reset), modify control parameters, enable or disable protections, set system variances, set communication variables, monitor system parameters such as line voltages and currents and access the fault queue.
Enters a menu or parameter, or saves a parameter change. Starts the motor. STOP Stops the motor, and resets a trip. 4.2 Operation 4.2.1 Display modes There are three display modes: the monitoring mode, the programming mode, and the fault history mode. Press the [MODE] key to switch between the display modes. On power up, the monitoring mode is shown by default.

4.2.4 Fault history mode The starter stores information on the 5 latest faults. Three of the latest faults are displayed in the fault history, See Figure 4.5. Figure 4.5 Fault history screen In the figure above: 1st -- The most recent fault stored in the fault history. 2nd -- Second most recent fault.

5.2 Start/Stop Options 5.2.1 Voltage ramp The voltage ramp provides soft starting of a motor by increasing the voltage applied to motor from the Initial Voltage setting (A03) to full (100%) line voltage. When the Starter receives a start signal, it quickly increases the voltage to the Initial Voltage setting (A03).

Figure 5.2 Current limit ★Note: Current Limit Starts are not recommended on variable torque load applications like fans and pumps. ★Note: Attempting starts with the Current Limit set to a value of 200% Rated Current (Ie) or lower are not recommended as the motor may not develope adequate torque to accelerate properly.
Page 27
5.2.4 Current ramp With current ramp starting, output voltage varies to provide a linear increase in current up to the Current ramp level (A07), and Current ramp time (A08) sets the speed of this linear current increase. The following figure shows the relationships of these different ramp settings.

Voltage kick start is only useful on motor loads that are hard to get rotating but then are much easier to move once they are rotating. An example of a load that is hard to get rotating is a ball mill. The ball mill requires a high torque to get it to rotate the first quarter turn (90°).

Modbus services APPENDIX A: The starter provides only a Modbus RTU to support remote communication. The data format is 8-N-1 (8 Data bits, No Parity, 1 Stop bit), Modbus address and baud rate are set individually in parameters C03, C04. A1 Modbus-RTU Frame The Modbus RTU frame contains no message header byte, nor end of message bytes.
• The receiving device recalculates a CRC during receipt of the message, and compares the calculated value to the CRC16 actual value it received in the CRC field. If the two values are not equal, an error results. A2 Modbus functions available Note: Hi = high order byte, Lo = low order byte.
