7.7.10 Encoder CAN

If this function is enable, it is possible to generate and receive the "encoder like" signals by
the CAN line, which replaces quadratures signal.
The running is transparent, respect to the traditional encoder signals: the CAN line must be
connected instead of quadratures signals, and must be considered that every encoder signal is
available every 1,024msec over the CAN, and the signal has 4byte for data.
It is possible to have up to a maximum of three encoder signals, if the speed of the CAN is
1Mbs, and only one encoder signal if the speed is 500kbs.
This function is not available when OPM15 is active.
The drive needs some bit and parameters about the correct operation:
b70.8: enable the encoder CAN function, it activates at the successive switching on
after save the setting of the bit.
b70.9: selects the counter by CAN or encoder input for the OPM.
b70.10: enable the encoder CAN virtual through the parameter pointed from Pr158.
Pr154: reduction ratio numerator of the input encoder counting by CAN.
Pr155: reduction ratio denominator of the input encoder counting by CAN.
Pr156:157: counter encoder CAN
Pr158: pointer to the parameter to send as virtual encoder on the CAN.
Pr159: speed encoder IN via CAN
