GENERAL

DESCRIPTION

A synchronous motor powers a drive shaft and a backlash­free cam shaft via a gear reducer.

The cam shaft operates limit and auxiliary switches. The
position at which one of the limit or auxiliary switches operates

can be adjusted steplessly within the operating range using
the associated cam disc. Manually adjustable lever-operated
cams or spindle-driven cams, which can be adjusted with a
screwdriver, are available.

FEATURES

• Position indicator

• Easily adjustable limit and auxiliary switches

• Synchronous motor

4) at 50 Hz for 90°
at 60 Hz, Drive times are about 20 % shorter

5) under nominal conditions
under extreme conditions (e.g. +60 °C, 230V -15%) the torques will be 25% lower

6) +10% -15%; 50...60Hz
at -15%; torque reduced by approx. 20% at undervoltage
