7.11.7 Initial setting
Adjust increments per revolution (Ec.01, Ec.11)
With this parameter the encoder line number is adjusted to the connected encoder within a range of 1…16383.
- Ec.01 for encoder interface 1
- Ec.11 for encoder interface 2
Incremental pulses are generated by the evaluation block for resolver which does not supply incremental
pulses. The number of the generated pulses is displyed in Ec.01 in this case.
The resolution of the resolver interface is adjusted via this parameter. A change is only possible when the mo-
dulation is switched off. Simultaneously with the resolution also the increments per revolution for emulation on
channel 2 changes.
Due to the high resolution the maximum speed is limited at channel 1. The following limit values are valid:
Resolution / bit Maximum speed / rpm
10 150000
12 60000
14 30000
16 7500
EC08 enc 1 excitation
The excitation frequency of the resolver can be adjusted in the range of 1.7 kHz to 19.5 kHz.
Default 10kHz.
Typically the rated frequency of the used resolver is adjusted here, usually 4, 5, or 10 kHz.
EC09 enc 1 signal level
The value for the encoder breakage recognition of the resolver to encoder channel 1 can be adjusted with this
parameter. E.EnC11 is triggered if the signal level of SIN or COS exceed with its maximum values this limit.
EC09 is normalized in Vpp of the signals.
The encoder signals are measured with value 0: auto and the threshold is set to the half measured value.
