Activating Encoder Emulation
It is possible to control the behavior of the function with the help of
parameter C014, Encoder emulation type.
C014 Encoder Emulation Configuration
0 0 0
Select Emulation
0 = no output
1 = incremental encoder emulation
2 = absolute encoder emulation
Dead-Time Compensation
0 = is deactivated
1 = is activated
Select Actual Position Source
0 = position output of motor encoder
1 = position output of optional encoder
2 = output of position command value
Operating Principle: Incremental Encoder Emulation
The number of graduation marks of the emulated incremental encoder
is set in parameter C015, Encoder emulation resolution:
• 1 to 65536 (=2^16) graduation marks / revolution
Note: If a motor with resolver feedback is mounted, then the
emulator generates as many zero pulses per mechanical
revolution as the resolver has pairs of poles. Therefore, make
sure that the input for C015, Encoder emulation resolution
is divisible by the number of resolver pole pairs with no
remainder, since otherwise the zero pulse will "run away".
The parameter unit depends on the motor type, i.e.,
• rotary motors: graduation marks / revolution
• linear motors: graduation marks / mm
Position of the Zero Pulse Relative to the Motor Position
With motor encoders that achieve an absolute, unambiguous position
within one motor revolution after initialization, or within one electrical
revolution with resolvers, the zero pulse is always generated at the same
motor position each time the unit is switched on.
