NPULSES (P8)
Indicates the number or pulses/rev provided by the rotary encoder. When using a linear encoder,
it must be set to ·0·.
It must be set when the drive's velocity command is analog or it is sent via CAN (DRIBUSLE = 0 or 1).
When using gear reduction on the shaft, only the whole assembly must be taken into account when
setting one of parameters PITCH or NPULSES.
DIFFBACK (P9)
Indicates whether the feedback device uses differential signals (double ended) or not.
SINMAGNI (P10)
Indicates the multiplying factor (x1, x4, x20, etc.) that the CNC must apply only to sinusoidal
feedback signal.
For square feedback signals, this parameter must be set to 0 and the CNC will always apply a
multiplying factor of x4.
The axis feedback resolution must be set using a.m.p. PITCH (P7), NPULSES (P8) and SINMAGNI
(P10) as shown in the following table:
Possible values
Integer numbers between 0 and 65535.
Default value: 1250
When using CAN servo, if both parameters NPULSES and PITCHB are set to ·0·,
the CNC will assume the equivalent values of the drive.
Value Meaning
NO It does NOT use differential signals.
YES It uses differential signals.
Default value: YES
Possible values
Integer numbers between 0 and 255.
