Mitsubishi LE-40MTB-E - Feed Reel Control

21
6.5 Feed reel control
The basic settings and connection are the same as those described up to section 5. Items particular to the
feed reel control are described below.
When using an auxiliary brake/clutch for the feed reel, it is convenient to adjust the output manually using
the new reel preset output NRO.
Connect the powder clutch (out feed)/brake (in feed)
of DC24V system 4A or less. (The same with the
hysteresis clutch/brake in the same manner.)
When the NRO output is used, use the following set-
ting. See page 9.
In feed : Unwinding, multiple reels
Out feed : Winding, multiple reels
When the servo motor operates
both at the resurrection and power
running sides, the control may be-
come unstable near zero. In such
case, use an auxiliary clutch or
brake for the feed reel so that the
control output is used either for the
resurrection side only or power run-
ning side only.
• For the feed reel control, use the "CONTL.PART" screen within "SWITCH" on the initial setting screen
or the engineer screen to set as follows:
• When the NRO is used, select "UNWIND" (unwinding) or "WIND” (winding).
