Description Of Specific Functions
V260 Series High Performance Closed-Loop Vector Inverter User Manual
184
The accrued pulse of subordinate motor in this mode is required to reset simultaneously with the master
motor. Thus, only need to operate in the master motor, or make use of the reset terminal of subordinate
motor.
FA.2.30 Coupling balancing gain
Setting range:
0.001~10.000
Factory default: 1.000
When the linkage balancing function is effective, this parameter is used to set the adjusting gain output by
this device, and it is only effective for the slave device. The higher the gain is, the higher the amplitude of the
self-balancing adjustment is.
7.41 EXPANSION MULTIFUNCTIONAL INPUT TERMINAL (GROUP
FB.0 AND FB.1)
The parameters in the access the corresponding extensions to take effect, its function and F3.Group the
same parameters.
7.42 SERVO CONTROL AND SCALE POSITIONING (GROUP FB.2)
Fb.2.18 Automatic shift switching
frequency
Setting range: 0~5.00Hz
Factory default: 1.00
Fb.2.19 Automatic shift switching
cycle
Setting Range: 0.10~2.00Sec.
Factory default: 0.3
For equipments with mechanical speed change gear like the spindle, during mechanical shifting, shift jogging
can be adopted to avoid mechanical dead. This group of parameters defines the running parameters for shift
jogging.
Fb.2.20 Torque at 0 Hz (DC
bind-type brake preferred)
Setting range: 0~3
Factory default: 0
Fb.2.21 Position lock
gain1(location gain)
Setting range: 0.10~10.00
Factory default: 1.0
0: Void
1: Bind-type brake torque effective
2: Position locking (PG feedback VC mode)
In the running mode of V/F and SVC, the function of zero frequency torque holdup is similar with that of the
DC braking function. It cannot guarantee that the motor shaft is absolutely static when it is dragged by the
load, and the position gain is void.
In the PG feedback VC control mode, if the zero frequency torque holdup 2 is selected, the drive will
automatically memorize the shaft position at stop, and shift to the position serve running mode, so as to
guarantee that the shaft will not rotate even under the load dragging.
The higher the position gain is, the stronger the locking torque is.
3: Lock in the designated stop angle
It is used to the spindle drive of machine tool to ensure the constant angle in the spindle off. The stop angle is
set by Fb 2.45.
