Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in /var/www/vhosts/lestercontrols.co.uk/httpdocs/vendor/zendframework/zend-stdlib/src/ArrayObject.php on line 426

Ziehl Abegg 4CS Drive

The new contactorless ZA 4CS drive is used on all types of installations whether it be for synchronous or asynchronous motors.

The easy-to-use keypad and compatibility with all ZA motors make for an easy solution on many installations. The recently introduced ZA REC unit makes the combination a perfect match for any regenerative installations. Like the HPV900 S2, direct-to-floor approach using serial communications is standard when used in conjuction with a CEDES or USP Shaft Positioning System.
