Frequently Asked Questions and Answers
- What supplies the power to vw3a3401 encoder interface card fitted on Altivar 71?
The encoder interface card VW3A3401 uses an internal 5VDC supply from the drive control block. The interface card supplies 5VDC to the encoder RS422 with maximum current available up to 200mA.

Issue: Control positioning Product Line: ATV71 Environment: All models and serial numbers Cause: None Resolution: No, the ATV71 with an encoder is used for accurate speed control and not for control of position. Contact the Automation group at (800) 468-5342 for systems to perform the positioning functions.
Read more - When does the Drive Overheat Fault (OHF) occur in Altivar 71 Drives.
The Drive Overheat Fault (OHF) indicates that the heat sink temperature has crossed the temperature threshold. This is the information from the temperature sensor located on the heat sink, near the transistor module. When the Thermal Heat Dissipation (THD) is greater than 118% it trips in OHF. 118% is approximately 100 Deg Centigrade temperature on the heat sink. The main causes for the occurrence of this fault are: 1. Excessive ambient temperature. (Provide proper air cooling of the control roo...
Read more - Altivar 61/71 what is the recommended corrective action when the motor runs in reverse with a run forward command?
Issue: The motor is running backwards with a forward run command on the drive. Product line: Altivar ATV61 and ATV71 Environment: All models, all serial numbers Cause: The phase rotation is inverted coming out of the drive going to the motor. Resolution: Option 1: To correct the motor rotation swap two motor leads on the drive output terminals. Option 2: Go in the simple start menu 1.1 find output phase rotation change it from ABC to ACB. Refer to the ATV61 and ATV71 programm...
