Terminal specifications
Since the terminal type changes from a screw type terminal to a spring clamp type terminal, stranded wires and bar type crimp
terminals are used for wiring. Therefore, when using a round terminal and Y terminal, terminal processing of the wiring is
necessary.

Specifications
Left Tension detector input
Connect the lead wires GR=green (blue) and
WH=white.
Right
Use the parameter to specify the number of
detectors to be used: one or two.
The connection varies depending on the
compression/tensile load. When one detector is
used, it is necessary to make a short circuit
between GRL and WHL.
For shield connection
External tension setting: 0 to full scale tension at 0
to 5 V DC
Internal resistance: 100 k
Recommended potentiometer (control): 5 V 10 k
Selection from reel diameter, stall, new-reel taper
ratio setting, and external tension
Recommended potentiometer (control) 5 V 10 k
Analog input common
Output for tension monitor
Filter adjustable by parameter
0 to 5 V DC
Load resistance: 1 k or more
Analog output common
Operation/stop: ON=automatic operation,
OFF=stop
Reel change signal: OFF=A reel, ON=B reel
Gain 1 operation: Gain 1 enabled during ON
Stall memory reset: About 0.5 second one-shot
input
Assigned by parameter settings and used.
• Gain 2: Gain 2 enabled during ON
• Inching: Output lower limit restriction, stall
memory update stop
• OUT remote: Control output ON during ON
• Cut torque: During ON, output lower limit
restriction, cutter
Contact input common

• Zero tension detection output: Set value 0 to
1999 N (199.910 N)
• Output ON at tension below the set value:
Always OFF when the set value is 0 (however,
the output is ON regardless of the set value and
tension when the watchdog timer is operating).
• Relay output (250 V AC 0.5 A or 30 V DC 0.5 A)

Terminal Specifications
GRL Left Tension detector input
• Input range switchable
WHL
(1) -150 to +150 mV DC (LX tension detector)
GRR Right
resolution: Approx. 7.90 V
(2) -15 to -15 mV DC (strain gauge) resolution:
WHR
Approx. 0.790 V
When only the detector on one side is used, it is
necessary to make a short circuit between GR and
WH on the other side.
The compression/tensile load is determined
automatically.
