Special Parameters - YASKAWA MOTIONPACK-110 Descriptive Information

5.3.3 ME, SF, TF SIGNAL DELAY TIME SETTING (#1100) 0__ SET VALUE <32767
When the M-code read signal (MF), T-code read signal (TF) or S-code read signal (SF) is
output after the M-BCD code output signal (M,, to M_8), T-BCD code output signal (T,, to
T_ ) or spindle speed command with a delay, the delay time is set by this parameter.
The delay can be set, with "1" representing 8 ms. For example, setting "2" means a
delay of 16 ms.

5.4 SPECIAL PARAMETERS
5.4.1 POSITION COMMAND UNIT SETTING (#1557, #1558, #1757, #1758, #1957, #1958)
(1) Generally, the position detection unit (distance per pulse) is determined by the drive
system and the position detector.
Witn Motionpack-110, two coefficients, B/A and A/B, are used to match the
position command unit for the drive system with the position detection unit. Fig. 5.2
shows a block diagram.
B/A represents the number of output pulses per the minimum input unit (e. g.,
0.001 mm), and represents the feed distance of the machine per pulse of quadruple PG.
Prior to determining the parameters, B/A and A/B should be calculated frome
the specifications of the machine and the detector in advance, and
x 16777216(integer portion only) __ __ 100
A
B × 16777216(integer portion only) (1-_0- __-_A B __100)
should be set as the parameter values.
Parameters for B/A for the X-, Y- and Z-axes are #1557, #1757 and #1957, and
those for A/B are #1558, #1758 and #1958, respectively.
