All the units should be grounded directly to a common ground terminal, as shown in the figure below. Ensure there are no ground loops. To Stop Method. External fault OFF The AC motor drive control wiring should be properly installed and not touch any live power wiring or terminals.

Make sure that the wiring is correct. In particular, check that the output terminals U, V, W. Verify that there are no short-circuits between terminals and from terminals to ground or mains power. Please choose a suitable method depending on application and operation rule.

The operation is usually used as shown in the following table. The counter value C. Displays the selected parameter. Displays the actual stored value of the selected parameter. External Fault. To set parameters In most applications, the user can finish all parameter settings before start-up without the need for re- adjustment during operation. The 12 groups are as follows Last used frequency saved. OL2 Enabled during accel. After the over- torque is detected, stop running.

Accumulative Motor Overheat Warning for Heat Sink Display the estimated value of torque in Nm as it relates to current. Input the correct password here to enable changing parameters. During Auto acceleration the torque is automatically measured and the drive will accelerate to the set frequency with the fastest acceleration time and the smoothest start current.

External terminals. RS serial communication RJ Page 94 Chapter 5 Parameters VFD-B Series Frequency Frequency frequency output motor speed frequency motor output speed stops according to operation free run to stop operation decel eration time command command When Pr. See Chapter 2 for definition of direction of rotation. Operation status is not changed even if operation command source Pr. With Pr. Page Chapter 5 Parameters VFD-B Series When the counter value reaches this value, the corresponding multi-function output terminal will be activated, provided one of Pr.

This multi-function output terminal will be deactivated upon completion of Terminal Count Value Attained. Case 1: Pr. Case 2: Pr. The whole scale of the potentiometer can be used as desired. In addition to signals of 0 to 10V and 4 to 20mA, the popular voltage signals also include signals of 0 to 5V, 4 to 20mA or any value under 10V. Negative slopes are used in applications for control of pressure, temperature or flow.

The sensor that is connected to the input generates a large signal 10V or 20mA at high pressure or flow. Terminals for external Base Block control. Refer to Pr. No error message is displayed. When parameter value Forced Stop N. Decel time 2 Accel time 3 Decel time 3 Accel time 2 Decel time 4 Accel time 1 The delay time is used to debounce noisy signals that could cause the digital terminals to malfunction.

The parameter settings are: Pr. Setting Pr. To stop the PLC program, one must either pause the program or turn it off. During acceleration, the AC drive output current may increase abruptly and exceed the value specified by Pr.

Over-Torque detection enabled during constant speed operation. If Pr. Under such circumstances, DC Brake can be used to hold the load in position before setting it in motion. This parameter should be set at a value to ensure that any residual regeneration voltage from the motors on the output has disappeared before the drive is activated again.

It will cause the AC motor drive to never remain within these frequency ranges with continuous frequency output. These six parameters should be set as follows Pr. A motor with high inertia will take a long time to stop completely. By setting this parameter, the user does not need to wait for the motor to come to a complete stop before restarting the AC motor drive. If a PG card and encoder is used on the drive and motor, then the speed search will start from the speed that is detected by the encoder and accelerate quickly to the commanded frequency.

Page For RS communication, please only use pin 3 and pin 4. The RS master then controls each AC motor drive according to its communication address. For example, 64 Hex.

Page 08H: loop detection 10H: write multiple registers The available function codes and examples for VFD-B are described as follows: 1 03H: multi read, read data from registers. Referencing to When the integral gain is set to 1 and the deviation is fixed, the output is equal to the input deviation once the integral time setting is attained. When min. Once a fault is detected, the corresponding protective functions will be activated. The following faults are displayed as shown on the AC motor drive digital keypad display.

The four most recent faults can be read from the digital keypad or communication. Make sure that the ventilation holes are not obstructed. Overheating Remove any foreign objects from the Heat sink temperature too high heatsinks and check for possible dirty heat sink fins.
