08-62 Detection Time of Broken Belt Unit: 0.1
Control
mode
VF VFPG SVC FOCPG
Factory Setting: 1.00
Settings 0.00~100.00 sec
Pr.08-59 is only valid when Pr.08-39 is not set to 0 and Pr.08-42 is set to 0.
When the broken belt detection is enabled, line speed is higher than Pr.08-60, allowance
difference of reel diameter of broken belt detection exceeds Pr.08-61 and detection time
of broken belt exceeds Pr.08-62, the broken belt occurs. When the broken belt occurs, it
will display “bEb” with free running. It can be used with the multi-function output
terminal setting 46 for broken belt detection.

Factory Setting: 100
Settings 0~100%
The corresponding value for the 100% of tension feedback is 10V.

When the error of tension PID target value and tension PID feedback exceeds Pr.08-63
and the allowance error detection time of tension PID exceeds Pr.08-64, tension PID
feedback error occurs. Refer to Pr.08-65 for error treatment of tension PID feedback. It
will display “tdEv” at this moment.
