Operating Instructions
Initial installation 2K2100 with STW
In most cases, however, the engaging gears in the
gearbox mesh as early as the first rotation
direction change, meaning that the shift time is
around 300 to 400 milliseconds. Mechanical gear
changes are performed by a shift unit on the
gearbox, driven by a 24V DC motor.
The gearbox shift components (axially moved,
toothed sliding sleeves) are positively engaged.
The shift positions are monitored by limit
switches in the shift unit. A time relay must be
provided to monitor the time lapse, i.e. if a shift is
not performed within 2 seconds from the
beginning of the shift, it is cancelled (if no signal
is received from the limit switch S1 or S2). A new
shift then has to be initiated. A time limit of 10
seconds must be provided for around 4 to 5
further shift attempts. If the gear change does not
take place within this time, the system has to be
checked. Check the oscillating movement (angle)
and the number of rotation direction changes. In
most cases, adjust based on the smaller value and
then repeat the shift attempt.
Shifting at low speed without oscillation is not
permitted as a perfect change cannot be assured
(flowchart for gear change, see section 3.7.6).
CAUTION
Once the limit switch signals are reached, there
should be a waiting time of 0.5 to 1.0 seconds
before the main spindle motor is enabled. The
limit switch signals must be monitored during
the operating time.
The limit switches must only be energized with
the control current (0.5 A) and not with the
change current (5 A).
The shift sequence must be monitored. If
necessary, a timer should be used to cancel the
shift sequence after approx. 2 seconds if there is
no limit switch signal (S1/S2). After this, new
shift command; main spindle motor may not be
enabled.
