12.1-12-15
 You can set Pr.12-42 = 1 when activating the tension function, by doing this to prevent the loose
rewinding / unwinding material or the value exceeds the setting range of Pr.12-45 from causing
the tension convergent time to be too long.
Example: Adjusts the value of Pr.12-44 and Pr.12-45 to make the tension feedback be in the
setting range of Pr.12-43, and PID control is effective at this moment.
 When Pr.12-42 = 2, in unwind mode, it’s allowable that the motor runs reversely to tightly roll the
material automatically.
12-46
Broken Belt Detection Function
Default: 0
Settings 0: Disabled
1: Enabled
12-47
Minimum Linear Speed of Broken Belt Detection
Default: 0.0
Settings 0.0–3000.0 m/min
12-48
Reel Diameter Error of Broken Belt Detection
Default: 100.0
Settings 1.0–6000.0 mm
12-49
Broken Belt Detection Time
Default: 1.00
Settings 0.00–100.00 sec.
 When Pr.12-21 ≠ 0 and Pr.12-27 = 0, Pr.12-46 is valid.
 The broken belt occurs when the linear speed is higher than Pr.12-47, the change of the reel
diameter exceeds Pr.12-48, and over the time setting in Pr.12-49. When broken belt detection is
enabled, if broken belt occurs, the drive shows “dEb” and ramp to stop. At the same time, you
can also set MO to be 46 as the indication of broken belt.
12-50
Tension PID Feedback Error Level
Default: 100
Settings 0–100%
12-51
Tension PID Feedback Error Detection Time
Default: 0.5
Settings 0.0–10.0 sec.
12-52
Tension PID Feedback Error Treatment
Default: 0
Settings 0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
 If the difference between the tension PID target value and tension PID feedback value exceeds
the tension PID feedback error level (Pr.12-50), and the error time exceeds the tension PID
feedback error detection time (Pr.12-51), then the PID feedback error is abnormal. “tdEv” displays
on keypad at this moment, the treatment refers to the setting in Pr.12-52.
