Some EC motors has tachometer output one pulse per revolution. • EMC-COMPATIBLE INSTALLATION OF EXTERNAL CONTROL LINES: The control cable must not be longer than 30 m. Screened control cables must be used when the cable length is longer than 20 m. When using a shielded cable connect the shielding to one side only, i.e. only to the device with the protective ground (keep cable short and with as little inductance as possible!). Pay atten- tion to sufficient distance from power lines and motor wires to prevent interferences. Attention! Ensure correct polarity! Never apply line voltage to analog inputs!The EC motor has electronically thermal-/over- voltage protection.2020-01-07 15:36:11 2020-01-07 15:36:11 2020-01-07 15:33:58F A U L T D E T E C T I O N1.
