4.4.8 Feedback Systems
The Series ECE10CM & DC10CM drive controls can be fitted with various types of feedback
systems. This results in different component variants for the converter:
♦ ECE10CM-00: Converter for permanently excited three-phase synchronous motors
with block commutation. Speed feedback via commutation
sensors.
♦ ECE10CM-01: Converter for permanently excited three-phase synchronous motors
with block commutation. Speed feedback via incremental
generator.
♦ ECE10CM-02: Converter for permanently excited three-phase synchronous motors
with sinusoidal commutation. Feedback with resolver.
♦ DC10CM-00 Converter for permanently excited DC motors without feedback.
Speed is controlled via EMF regulation with IxR compensation
♦ DC10CM-01 Converter for permanently excited DC motors
Feedback by means of DC tachogenerators
4.4.8.1 Commutation Sensors (ECE10CM-00)
If a permanently excited three-phase synchronous motor (ECE) with 3x120° offset
commutation sensors is connected, a control range of 1:40 can be achieved.
The commutation sensors shall be connected to the drive control in accordance with the
following sketch. The sensor cables must be screened.
SC (X3-1) Commutation sensor inputs with internal
SB (X3-2) Pull-Up resistors 1 kΩ, 15 V reference voltage
SA (X3-3) HIGH with input signal > 12 V
LOW with input signal < 1 V
GND (X3-4) Reference potential
+15V (X3-5) Sensor supply
