Wiring shown above the terminal strip indicates internal wiring on the main control board. This means that the drive will operate with any phase sequence of the incoming three phase voltage. Snubbers are typically available from the manufacturer of the device. Below 100, the value can always be changed by tenths of units. This will give the drive a stop command at the same time the device opens, and will not allow the drive to start again until the device is closed. Motor cable or armature is shorted to ground. They are readily available from suppliers of electronic components.
Recommended control wire is Belden 8760 2-wire or 8770 3-wire , or equivalent. Replace fuse or reset the breaker. Energize the incoming power line. Output Transistor Fault: Phase to phase or phase to ground short circuit on the output; Failed output transistor; Boost settings are too high; Acceleration rate is too fast. For 120 Vac single phase input models, use terminals L1 and N. Refer to the wiring diagrams in Section 11.
The drive will then accelerate through the skip range to the new speed. Warning of hazardous electrical Consequences if disregarded:. Opens if there is no fault condition. This method must be used if it is necessary to toggle between two speed sources. The speed pot can be 2. Severe damage to the drive will result. The first part is the software version, and the second part is the revision number.
Please contact the factory for more information on troubleshooting faults. The options are listed by baud rate, number of data bits, parity, number of stop bits, and whether the watchdog timer is enabled or disabled. Fans or blowers should be used to insure proper cooling in tight quarters. A blown stator will show a burn mark. At the end ofthe 500ms interval, the relay will de-energize if the drive is no longer in current limit.
Wait three minutes after disconnecting incoming power before servicing drive. The follower drive uses this voltage reference to set the speed of the follower motor. The interval between restart attempts is 15 seconds for setting 04, and 2 seconds for settings 05, 06 and 07. See the example below: Example: A 0-100 psi transducer outputs 4 mA at 0 psi and 20 mA at 100 psi. Failure to heed this directive may result in fire or serious injury. Possible Causes Troubleshooting 37 Suggested Solutions 3.
Refer to Parameters 06 and 13 in Section 15. The following wiring diagram examples provide a quick reference to wire the drive for the most common configurations. Defective capacitor Test capacitor per previous instructions. The wiring and corresponding parameter settings are given. Below 100, the value can always be changed by tenths of units. Wait three minutes after disconnecting incoming power before servicing drive.
The following functions can be selected. The faults are stored from newest to oldest, with the first fault shown being the most recent. If the M button is held down, the speed setpoint will decrease by tenths of Hz until the next whole Hz is reached, and then it will decrease by one Hz increments. Replacing these items on drives that are under warranty will void the warranty. Disconnect power from the drive and allow time for the voltage on the capacitors to dissipate before working on the drive. The motor is at zero speed.
This results in the first digit reading from left to right of the value disappearing from the display. When possible, disconnect the voltage input from the drive before adjusting the trimpots. Remove power from the drive. See Parameter 48 for 50 Hz base frequency. Obey all safety messages that follow this symbol to avoid possible injury or death.
For field motor connections, see Table 2 on Page 9. May be able to reassemble; otherwise, motor should be replaced. Example 1: The drive is running and the present speed source is the keypad. Voltage fluctuation must not vary by greater than 10% overvoltage or 15% undervoltage. Make sure that the switch is not loose on the shaft.
If the rating, contact your assistance. The watchdog timer will stop the drive after 10 seconds of no serial activity to safeguard against a failed serial link. This will cause the horsepower capability of the motor to remain approximately constant. If the drive is rated for single and three phase input, wire to terminals L1 and L2 for single phase input, or wire to terminals L1, L2, and L3 for three phase input. This is a linear function, so at 30 Hz the display would read 87. This results in a speed range from 20 Hz to 22 Hz that the drive will not operate within continuously. Integral Gain Parameter 65 is used to force the steady-state error to zero by increasing the output speed command with respect to time.
