8.3.1 Rotary table operation

This section describes the operation of the rotary table.

(1) Operation

(a) A rotary table outputs a travel value which is the product of the drive module

travel value and the gear ratio of the transmission module.

[Rotary table travel value] =

(b) If a clutch is used, the rotary table is controlled from the point at which the

clutch is turned ON.

(2) Control details

(a) The feed current value is maintained on switching from the real mode to the

virtual mode or from the virtual mode to the real mode.

(b) Backlash compensation processing is continued in accordance with the

settings made in the fixed parameters regardless of switches between the

real mode and virtual mode.

(number of PULSES per rotary table revolution).

Make it the same value as the travel value per PULSE in the fixed

parameters.
