Stepper motor amplifier
max. 2 000 VA, IP20 | LV-Unit Series
IEF Werner
The power amplifier LV-UNIT is used for driving up to four 2, 3, or 5 phase stepper motors. All connections are on plug-contacts for easy maintenance. A 7 segment status display on the front provides information on the operational readiness of the power parts and the integrated power units thus ensuring reliable and speedy diagnosis. The brake drive is a standard configuration of all versions. The integrated power units provide the voltages for external use and for the respective motors. Due to the internal fan for cooling the power electronics the power amplifier can be installed in any position on a rack, horizontal or vertical. The LV-UNIT equipped with a separate rotation control connection monitors the implementation of the position steps for motors with encoders that are stipulated by the control electronics (e.g. PA-CONTROL). Possible step loss and faults in mechanical or electronic equipment are therefore recognized promptly by the control. Four light-emitting diodes on the power output stage provide information on the dynamic status of the drive.
