Spindle Gear Change - YASKAWA MOTIONPACK-110 Descriptive Information

Normal rotation, reverse rotation, and stop of the spindle are controlled by using
input signals and parameters. For details of S -function, programming, input, and
parameters, see Pars. 4.5, 9.2.2, 5.3 and 5.8, respectively.
NOTE
1. The function does not contain acceleration/deceleration. Use a spindle
drive with the acceleration/deceleration function as required.
• 2. The D/A output of the standard axis module (Type JEFMC-B011) is
adjusted to a maximum +--5 V. To use a spindle drive with 10V input,
prepare the axis module (Type JEFMC-BOllB) that the D/A output is
adjusted to +- 10V, and --+15 VDC external power supply.
3.11.1 NORMAL ROTATION, REVERSE ROTATION, AND STOP OF SPINDLE
Normal rotation, reverse rotation, and stop of the spindle are controlled by setting axis
module D/A output to the positive side ( + ) , negative side ( - ) , and 0V, respectively,
using the spindle normal rotation signal (FRN), spindle reverse rotation signal (RRN),
spindle stop signal (SSTP), and parameter #2004 in combination when the spindle rotation
speed is programmed with S. A standard Servopack is used for spindle without adjustment.
When the drive unit only for the spindle is used, normal rotation signals should be
always input to Motionpack. The noral rotation, reverse rotation, and stop command of the
spindle that M-BCD output of M-signal (M03, M04, M05 etc.) in programming are decoded
can be controlled by input directly to the spindle drive unit.
3.11.2 SPINDLE GEAR CHANGE
The speed command voltage can be changed in accordance with spindle gear change. Gear
change can be made at three stages (L, M, and H) by using gear ratio selection signals
GR1 and GR2. The maximum rotation speed of the spindle for each of L, M, and H is set by
using parameters #2150, #2151, and #2152.
The speed command voltage on each gear is as follows:
S 5-digit Programmed Value (rpm) × Axis Module
Speed Command Voltage= Each Gear Parameter Setup Value (rpm) Max D/A output
The axis module maximum D/A output is as follows:
• +-hV: axis module type JEFMC-B011 (standard)
• +-10V: axis module type JEFMC-B011B
