Beckhoff AX5000 Series Function Manual

Motor types and operation modes
Function description 61
Version: 1.5
12 Motor types and operation modes
In this chapter the relationships between physical motor types, feedback systems and the necessary
operation mode will be explained.
Functionality from firmware v2.12
The firmware V2.12 enables the operation of voice coil motors with feedback system and (a)synchronous
servomotors with and without feedback (sensorless regulation).
Structure of the parameter P-0-0050 (Motor construction type)
The functional principle of
the motor
(asynchronous/synchro-
nous) and the type of con-
struction (rotary/linear) are
defined in this parameter.
Structure of the parameter P-0-0451 (Current controller settings)
In Control mode the opera-
tion mode is selected in rela-
tion to the predetermined
motor type (P-0-0050).
Please refer to the
table below for
the relationships.
Relationships between motor type and operation mode
Case Motor type Settings in P-0-0050 Settings in P-0-0451
1 Rotary synchronous servomotor with feed-
back
Functional principle = 0: synchronous
Construction = 0: rotary
Functional principle replacement = 0 (Default)
Control mode = 0: Field-ori-
ented current control with
feedback
2 Linear synchronous servomotor with feed-
back
Functional principle = 0: synchronous
Construction = 1: linear
Functional principle replacement = 0 (Default)
Control mode = 0: Field-ori-
ented current control with
feedback

1)
Rotary synchronous servomotor without
feedback
Functional principle = 0: synchronous
Construction = 0: rotary
Functional principle replacement = 0 (Default)
Control mode = 4: Field-ori-
ented current control without
feedback
4 Rotary asynchronous servomotor with
feedback
Functional principle = 1: asynchronous
Construction = 0: rotary
Functional principle replacement = 0 (Default)
Control mode = 0: Field-ori-
ented current control with
feedback

2)
Rotary asynchronous servomotor without
feedback
Functional principle = 1: asynchronous
Construction = 0: rotary
Functional principle replacement = 0 (Default)
Control mode = 2: U/f control
or
Control mode = 3: U/f control
with independent feedback

3)
Rotary voice coil servomotor with feedback Functional principle = 0: synchronous
Construction = 0: rotary
Functional principle replacement = 1: VoiceCoil
Control mode = 5: Current
control with feedback

3)
Linear voice coil servomotor with feedback Functional principle = 0: synchronous
Construction = 1: linear
Functional principle replacement = 1: VoiceCoil
Control mode = 5: Current
control with feedback
1): It is absolutely necessary to set Mode in parameter P-0-0464 to 1: EMF-based observer.
2): In the case of an asynchronous servomotor and the operation mode U/f control with independent
feedback (setting in P-0-0451), an independent external encoder can additionally be read.
3): As soon as you select a voice coil motor in parameter P-0-0050 the range in Functional principle
(synchronous / asynchronous) will be overwritten.
