Actuators NK and VK, Position Controller ESR-NK
3.4.4 Actuator motor
Alternating current
Important information!
Frequency fluctuations affect the positioning time of the device.
Synchronous motor with permanent-magnet rotor
230 V AC ±10%, 50/60Hz ±5%
115 V AC ±10%, 50/60Hz ±5%
24 V AC ±10%,
50/60Hz ±5%
Duty cycle: see nameplate of the actuator
NOTE
–
The specified voltage range of ±10% must always be maintained!
–
An overload of the actuator and strong voltage fluctuations may result
in a reversal of the rotational direction of the motor. This could damage
the actuator and/or the valve.
Direct current
Important information!
–
When stopped, the DC motor does not have any holding torque!
–
The DC motor is not suitable for short operating times!
–
Frequent or short-term switch-over from clockwise to counterclockwise
rotation and vice versa will result in demagnetization of the permanent
magnets.
–
Voltage fluctuations affect the positioning time of the device.
Commutator motor with permanent-magnet stator
24V DC ±10%
Duty cycle: see nameplate of the actuator
