after count down end.
Enter button（３） Press Target speed setting buttons to
specify Target speed. It is
recommended to set the speed far
from actual output speed in order tocheck pilot motor behavior.
Pilot motor start running, inching, and stop at target speed, when leads
are wired correctly and all parameters in Speed Setter are correctly set.
・ Turn off power switch immediately, when output speed doesn't
approach the target speed. Change the leads to terminals:U and V inorder for pilot motor to change rotation direction.
（４） Repeat (2) and (3), when changing wiring connection to U and V.
Also it is recommended to change "Target speed" couple times for making
shure entire system works.
（５） When using ＤＣ４～２０mA input signal to change "Target speed", switch
operation mode to "Auto(4-20mA)" and check again.
（６） Activate interlocking so that power is provided to both "Speed setter" andBeier main motor. Adjust "Start Timer" if necessary. (See section 710:"Start Timer"). It may be recommended to adjust the timing with load,
since acceleration time may vary depending upon the load.

9６－２: How Pilot motor approach target speed（１） Pilot motor runs continuously to approach the target speed, and starts
inching, when actual output speed reaches ±3% of target speed.
（２） Pilot motor stops, when actual output speed reaches ±0.5% of the target
speed.
（３） Pilot motor keep stop while actual output speed is within hysteresis range±3% of target speed. It will start same process(1) and (2), when actual
output speed is out of the hysteresis range.
（４） The Hysteresis range ±3% is factory default, and can be adjusted. See
section 7-5 to adjust the range.

７－４）"Minimum Speed" and "Maximum Speed"（１） General
Minimum Speed and Maximum Speed are speed range that "Speed
Setter" can control speed of "Beier variator" for.
Default value at Sumitomo factory shipment:
Min speed: minimum speed (Hz) that is same as Sumitomo catalog
Max speed: maximum speed (Hz) that is considering motor slip andlittle lower than catalog max. speed
When changing the parameter, understand the concept below and bothspeeds should be located within Beair Variator can provide, or it may
cause that Pilot motor never stop and damage Pilot motor and/or Beiervariatori.e.
"Beier variator min. speed" ≦ "Speed Settet min. speed" and"Speed setter max. speed" ≦ ”Beier variator max. speed"
It is required to set frequency (Hz) for both minimum and maximum speed
those are compared with feedback from electric magnetic sensor.
The feedback from Electric magnetic sensor is the number of gear teeth
pass per second (Hz) and the gear is mounted at Beier output shaft.
The feedback P is calculated by formula:Pmin = Nmin x Z / 60
Pmax = Nmax x Z /60
where
Pmin: Minimum shaft speed (Hz), Pmax: Maximum shaft speed (Hz)Z: Sensor Gear teeth number
Z1: Cyclo Reduction Ratio: 6,8,11,13,15,17,21…
Nmin: Minimum output shaft speed (r/min)Nmax: Maximum output shaft speed (r/min)

When sensor is located at intermediate shaft, then the shaft speed isgiven by formula:intermediate shaft speed = Output shaft speed x Cyclo reduction Ratio
The feedback P is calculated by formula:Pmin = Nmin x Z x Z1 / 60
Pmax = Nmax x Z x Z1 / 60
