Motor operation
The frequency converter generates a frequency/amplitude adjustable 3-phase AC voltage for the motor from the single or 3-phase main voltage supply. Motor speed
and thus actuator output speed are internally adjusted via the frequency.
Motor protection
The motor has a thermistor-type motor protection against thermal damage. The winding temperature is monitored continuously by the microcontroller. The response
after exceeding the permitted winding temperature is programmable on the PROFITRON. On the ECOTRON the motor protection cannot be inhibited.
Motor space heater (programmable for PROFITRON, for ECOTRON only with option „M18“)
The microcontroller continuously monitors the current winding temperature by means of a temperature sensor integrated in the motor winding. When the motor space
heater is activated by the program, the motor winding is heated by a DC voltage via the frequency converter depending on the cooling characteristic of the motor
winding when the motor is switched off.
1) full torque for voltage fluctuations between –30 % and +15 %
(in case of undervoltage from U
N
–30% to –10%, operation may be performed at reduced output speed n)
2) lower voltage increases the current, higher voltage reduces the current
3) starting current I
A
≤ nominal current I
N
4) at 35% of the maximum torque T
C max.
5) maximum current I
