Table top direction of rotation
Standard design: Direction of rotation clockwise
After connection of the motor: Check the table top direction of rotation.
If the table top rotates in the opposite direction, the connections of 2 phases (e.g. L1
and L2) must be changed on the network terminals.
Should the rotary indexing table rotate counter-clockwise this must be indicated in
the order or the end trip cam must be readjusted.
During pendulum mode the end trip cams are parallel, i.e. the signals S10 and S12
are emitted at the same time.
A change in direction of rotation during the rotational
movement leads to the destruction of the driving elements.
1.5.10
Holding phase of the operating cam
The middle of the holding phase is identified by a pointer at the drive shaft and a
STOP sign on the fixing flange.
Division 2 to division 12:
In the case of a rotation of the operating cam the table top continues to perform a
cycle by one partial step. The middle of the holding phase is identified by a pointer at
the drive shaft and a STOP sign on the fixing flange.
As from division 16:
In the case of a rotation of the operating cam the table top continues to perform a
cycle by two partial steps. In this case the trip cams for the end switches are
designed in such a way that two pulses are emitted during one rotation.
