12.1-12-14
12-38
Automatic Reel Diameter Compensation
Default: 0
Settings 0: Disabled
1: Enabled
 This parameter is valid only when Pr.12-00 = 1 and Pr.12-19 ≠ 0. If the mechanical gear ratio or
the linear speed is not accurate enough, you can use this parameter to compensate the reel
diameter.

12-39
Reel Diameter Calculation Delay Time
Default: 0.0
Settings 0.0–6553.5 sec.
 Starts to calculate the reel diameter after canceling the pre-startup and delaying time set in this
parameter.
 Sets this parameter to delay the time to calculate the reel diameter, and prevents from causing
inaccurate reel diameter or instability condition in a short time after the pre-startup stops.

12-40
Current Reel Diameter
Default: 1.0
Settings 1.0–6000.0 mm
 When the drive is not at STOP status, this parameter is read only.

12-41
Minimum Output Frequency for Reel Diameter Calculation
Default: 1.00
Settings 0.00~599.00 Hz
12-42
Pre-startup Mode Selection
Default: 0
Settings 0: Disabled
1: Pre-startup of rewind mode
2: Pre-startup of unwind mode
 When Pr.12-42 = 2, the output frequency limit is Pr.08-67.
12-43
Switching Level for Pre-startup and PID Enablement
Default: 15.0
Settings 0.0–100.0% (according to Pr.12-05)
 Example:
The tension feedback value is 0–100% that the lower value has loose tension and the larger value
has more tight tension. If Pr.12-05 = 50%, Pr.12-43 = 10%, then the range to pre-startup is 0–40%.
12-44
Pre-startup Frequency
Default: 2.00
Settings 0.00–599.00 Hz

12-45
Pre-startup Acceleration Time
Default: 3.00
Settings 0.01–600.00 sec.
