4.8.5 Operation mode spindle positioning (M19 command)
With activating of Z109.1– Operation Mode Set = -6 (spindle positioning) the drive switch-
es to position control (if not yet active), synchronizes thereby with the actual speed set
value and begins to slow down to
Z149.4– Spindle positioning speed. If this speed is
reached the drive positions to Z149.3– Spindle angle position considering Z149.2–
Mode.
The message „in position“ will be set from the drive in Z149.1– when
– the position set value reaches Z149.10– Active target position
and
– the position actual value is located in the Z121.5– Positioning window in the
Z121.6– Positioning window time.
The message „in position“ is also available in bit 10 of Z108.3– Status word 1.
From the following operation modes:
position control Z109.1– = -4
speed control Z109.1– = -3
position set mode Z109.1– = 1
speed set value Z109.1– = 2
jogging mode Z109.1– = 5
homing mode Z109.1– = 6
synchronous operation Z109.1– = -5
current control Z109.1– = -2
online-switching at speed actual value 0in the operation mode spindle positioning is
synchronized (shock-free) possible.
The spindle positioning has the following functions:
m Selection of the speed profile: Trapezoidal or S-curve.
m Absolute and relative types of following positioning without change of the operation
mode is possible.
m Free definition of the direction, if the speed actual value = 0, i.e. speed = 0 message
is available. Positive or negative direction and shortest distance to the angle target
respectively.
