- Type A and Type B
As described in the basic procedure, type A differs from type B in that the
servo used for B-axis position control is turned on or off at the different
timing.
Type A is suitable for a system in which the B-axis is clamped with shot
pins.
Type B is suitable for a system in which the B-axis is clamped with a clutch.
- Minimum indexing angle
The minimum index table indexing angle set in parameter No.5512 is used.
An integral multiple of a set value can be specified as an indexing angle. If
a value other than an integral multiple is specified, an alarm (PS1561) is
issued.
- Indexing axis setting
Be sure to set a rotation axis as an index table indexing axis.
(Set bit 0 (ROTx) of parameter No. 1006 to 1.)
- Absolute/incremental programming
Setting G90, bit 4 of parameter No. 5500, specifies absolute programming,
and override the G90/G91 G-codes.
- Indexing direction
If a value other than 0 is set in the M code for specifying negative direction
rotation (parameter No.5511), movement in the negative direction is made
only when a move command is specified together with the M code. In this
case, movement is performed in the negative direction, regardless of whether
absolute/incremental programming is used.
