INPREV1 (P72)
INPREV2 (P74)
INPREV3 (P76)
INPREV4 (P78) These s.m.p. indicate the entry speed for each gear.
The equivalent parameter at the drive is NP121.
OUTPREV1 (P73)
OUTPREV2 (P75)
OUTPREV3 (P77)
OUTPREV4 (P79) These s.m.p. indicate the exit speed for each gear.
The equivalent parameter at the drive is NP122.
3.7 Setting the feedback resolution of the axes
If parameters NPULSES and PITCHB are set with a ·0· value, the CNC
will assume the equivalent ones of the corresponding axis drive.
PITCHB (P86) This a.m.p. sets the ballscrew pitch when using Can regulation.
PITCH (P7) This a.m.p. sets the resolution of the linear encoder when the axis
feedback is taken to the CNC (DRIBUSLE=0). It does not define the
leadscrew pitch, which is defined with a.m.p. PITCHB (P86).
NPULSES (P8) This a.m.p. sets the number of encoder pulses when the drive's
velocity command is sent out via Can (DRIBUSLE = 0 or 1). When
using a linear encoder, it must be set to ·0·.
ABSOFF (P53) This a.m.p. will be required when using absolute feedback at the motor
encoder.
In order for the CNC to show the position of the axes with respect to
the machine reference zero (home), this parameter must be assigned
the position value (coordinate) of the machine reference zero with
respect to the "zero" of the linear encoder.
3.8 Communication channels via Can
‡ ‡ ‡ ‡
Synchronized channel
Fast channel, synchronized with the position loop used to transmit
the axis control data (speed, feedback, etc.).
At every loop time, the CNC transmits to the drive through this
channel the World Control (Speed Enable, Drive Enable, Homing
Enable, bit handshake) and the velocity command. The drive
transmits to the CNC the Word Status and the position value. The
transmitted data depends on a.m.p. DRIBUSLE (P63).
‡ ‡ ‡ ‡
Fast service channel (cyclic channel)
At every loop time, this channel transmits data (basically variables)
previously defined by the PLC's read-only machine parameters
plc.m.p SRR700 (P28) to SRR739 (P67) and write parameters
SWR800 (P68) to SWR819 (P87).
This data is updated via Can at every position loop.
The number of variables defined in this channel is limited
depending on the number of axes, on the sampling period selected
by g.m.p. LOOPTIME (P72) and on the transmission speed set by
g.m.p. CANSPEED (P169). A data overflow causes an error at the
CNC.
Possible values: ±99999.9999 mm or ±3937.00878 inches.
By default: 0.
