Wind Mode
Factory Setting: 00
Settings 00 Rewind
01 Unwind
Rewind/unwind mode should be selected according to different occasions. The reel diameter
increases gradually in rewind mode, and decreases in unwind mode.
10 - 23 Mechanical Gear Ratio A (at motor side) Unit: 1
Settings 1 to 65535 Factory Setting: 100
10 - 24 Mechanical Gear Ratio B (at load side) Unit: 1
Settings 1 to 65535 Factory Setting: 100
Mechanical gear ratio G=mechanical gear ratio B/mechanical gear ratio A=Pr.10-24 / Pr.10-23.
The two parameters must be set correct in tension control.

10 - 25 Source of Tension PID Target
Factory Setting: 00
Settings 00 Parameter setting (defined by Pr.10-26)
01 Via analog input AVI
02 Via analog input ACI
03 Via analog input AUI
04 Via RS-485 serial communication (defined by Pr.10-26)
This parameter determines the reference value of tension detection signal in PID feedback
control.

Tension PID Target Value Unit: 0.1
Settings 0.0 to 100.0% Factory Setting: 50.0
When Pr.10-25 is set to 00/04, tension PID target value is defined by this parameter.
