General Information
The transistor servo amplifier
SERVO-TV3.2
forms together with the direct current
servomotor a propulsion unit distinguished by its high regulating quality
The physical characteristics correspond to those of the direct current motors, that is, the
current is proportional to the torque and the voltage is proportional to the speed. Current
and speed can be measured precisely,
The tachometer actual value is generated from the sensor unit.
(incremental encoder with rotor position track or resolver.)
The analogue regulation circuits of the servo amplifier are designed simply.
In the speed controller (P-I-controller) of the servo-amplifier the nominal value and the
actual value are processed. The result is the current nominal value.
As occurs in all DC-servo-amplifiers which are supplied by the dc-bus ,
the feed-back of the energy must be observed when braking in the dc-bus (especially
where stroke or eccentric cycles are concerned). The ballast circuit is designed for 3%
on-period, higher cyclic durations can be reached by adding external resistors. (option)
