What is EEF1 fault on Altivar 71 drive.
EEF1 is a control EEprom Fault and at starting, the microprocessor on the application board tries to read and write to the EEPROM. If it is impossible,...
What is CLF fault on the ATS48 Soft Starter.
  CLF is Control Line Failure. • The ATS48 monitors the control voltage via the 2 terminals (CL1-CL2) on the 'control unit'. • This fault is encountered...
What is the difference between the I/O mode and separate mode in the Altivar71 drive.
The difference between the I/O mode and separate mode is the means to control the drive: - In separate mode the reference and the command can be sent...
Is it possible to use single Altivar 71 drive on two motors with one encoder in FVC mode (closed loop).
Yes, It is possible to use the encoder with 2 motors in parallel but only if the 2 motors are MECHANICALLY CONNECTED (rigid connection and not by...
