6.9 Servo winding and unwinding, two-reel switching
The control output from the terminal SA is input to the TLAP of the reel A or reel B servo amplifier through
the reel change, and controls the servo motor torque.
To stop the previous reel, set the speed limit command to 0 and give another torque limit input separately
as described on page 18.
The NRO output is to give the torque limit value while the new reel is in the preparatory drive operation. The
servo motor speed limit input (VC) should be controlled so that the rotational speed of the preparatory drive
(pre-drive) is commensurate with the spindle speed.
When the NRO output is used, select the control reel setting to multiple reels. See page 9.
See "Use of AC servo motor" on page 18 for the operation of the servo motor.
• Use the “REEL NUM.“ ( Number of reels ) screen within "SWITCH" in the initial setting screen or the
engineer screen to set reel switch-over or change the setting. Select "REELS“ ( multiple reels ).
• Use the “NEW R.SET” ( new reel set ) screen on the operator screen to set or change the new reel
preset value. Refer to the guideline for controller setting on page 15 to determine the settings.
• Use the "PRESET T" screen within "REEL CHANGE" on the engineer screen to set or change the pre-
set time. Set a relatively longer time than the actual switch-over time to include a margin.
