Fb.05
Set length
Range:0m~65535m
Default:1000m
Fb.06
Actual length
Range:0m~65535m
Default:0m
Fb.07
Number of pulses per meter
Range:0.1~6553.5
Default:100.0
The preceding parameters are used for fixed length control.
The length information is collected by X terminals. Fb.06 (Actual length) is calculated by dividing the
number of pulses collected by the X terminal by Fb.07 (Number of pulses each meter).
When the actual length Fb.06 exceeds the set length in Fb.05, the output terminal allocated with
function 10 (Length reached) becomes ON.
During the fixed length control, the length reset operation can be performed via the X terminal
allocated with function 28. For details, see the descriptions of F4.00 to F4.09.
Allocate corresponding X terminal with function 27 (Length count input) in applications. If the pulse
frequency is high, X5 must be used.
Fb.08
Set count value
Range:1~65535
Default:1000
Fb.09
Designated count value
Range:1~65535
Default:1000
The count value needs to be collected by X terminal. Allocate the corresponding X terminal with
function 25 (Counter input) in applications. If the pulse frequency is high, X5 must be used.
When the count value reaches the set count value (Fb.08), the output terminal allocated with function 8
(Set count value reached) becomes ON. Then the counter stops counting.
When the counting value reaches the designated counting value (Fb.09), the output terminal allocated
with function 9 (Designated count value reached) becomes ON. Then the counter continues to count until the
set count value is reached.
Fb.09 should be equal to or smaller than Fb.08.
Fb.10
Speed/Torque control selection
Range:0~1
Default:0
It is used to select the inverter's control mode: speed control or torque control.
0: speed control
1: torque control, when using this mode, you need to set F0.01 to 0.
The JT550 provides DI terminals with two torque related functions, function 29 (Torque control
prohibited) and function 46 (Speed control/Torque control switchover). The two DI terminals need to be used
together with A0.00 to implement speed control/torque control switchover. If the DI terminal allocated with
function 46 (Speed control/Torque control switchover) is OFF, the control mode is determined by Fb.00. If
the DI terminal allocated with function 46 is ON, the control mode is reverse to the value of Fb.00.
However, if the DI terminal with function 29 (Torque control prohibited) is ON, the inverter is fixed to
run in the speed control mode.
Fb.11
Torque setting source in
torque control
Range:0~7
Default:0
Fb.12
Torque digital setting in
torque control
Range:-200.0%~200.0%
Default:150.0%
Fb.11is used to set the torque setting source. There are a total of eight torque setting sources.
The torque setting is a relative value. 100.0% corresponds to the inverter's rated torque.The setting
range is -200.0% to 200.0%, indicating the inverter's maximum torque is twice of the inverter's rated torque.
If the torque setting is positive, the inverter rotates in forward direction. If the torque setting is
negative, the inverter rotates in reverse direction.
•
1: Digital setting (Fb.12) : The target torque directly uses the value set in Fb.12.
•
2: AI1
•
3: AI2
•
4: AI3
•
5: Pulse setting (DI5)
•
6: Communication setting
The target torque is set by means of communication.
The data format is -100.00% to 100.00%. 100% corresponds to the value of Fb.12.
