6.4 Explanation on the function of trimmer
VR1 : N max - Setting for maximum motor rotation speed
VR2 : Accel - Setting for acceleration gradient ( when S1-2 AD is selected )
VR3 : Decel - Setting for deceleration gradient ( when S1-2 AD is selected )
VR4 : N min - Setting for minimum motor rotation speed
VR5 : N gain - Setting gain of trimmer amplitude ratio
VR6 : I max - Setting for the maximum operation current of the device
VR7 : I x R - Setting for speed compensation ratio according to load under
armature voltage feedback (EM-1)
VR8 : I time - Setting I limit value delay time scope
VR9 : I limit - Setting limit for motor load current
VR10 : F-Ea - Setting armature voltage scope under operation as constant
output type
VR11 : F-I - Setting field rated current
VR12 : F-L - Setting minimum field loss
VR60 : N-OUT - Setting output voltage ( 0
∼
10[V] ) for speed meter (No. 35)
VR93 : LOAD OUT - Setting output voltage (0 ~ 10[V]) for load meter (No. 34).
VR90 : JOG - Setting rotational speed of JOG operation
VR91 : EX-SP - Setting analog conversion output value
VR92 : EX-OS - Setting analog conversion input offset
R130 : FVP - Setting gain of field current amplitude ratio
6.5 Explanation on the Adjustment of Device
Though this device is set to default at shipping, it can be readjusted according to the
following when there is a need for readjustment on the site.
[Caution] Since adjustment is dangerous when the motor is connected to a load,
adjustment under non-load condition is recommended.
6.5.1 Setting Field Rated Current (F-I) and Minimum Field Loss(F-L)
Applicable when the motor has separately excited field
◆
Setting field rated current ( F-I )
-. Input control power supply ( L1.1 / L2.1 / L3.1 ) and field power supply
( FL1 / FL2 ).
-. Turn on ENB terminal for preparing drive operation ( TB1 24 ).
