Main Sheave Diameter
Settings 100–2000 mm
Elevator Rated Speed
Settings 0.10
 Elevator speed (m/sec. = m/min. / 60)
Maximum Current during Acceleration
Settings 50–200%
 Measures motor's maximum current when the elevator is under test in automatic mode.
Mechanical Inertia Ratio
Settings 1–300
 The drive calculates the mechanical inertia by entering motor parameters, suspension ratio, gear
ratio, main sheave diameter, elevator speed, and maximum current during acceleration. You can
use Pr.13-30 to adjust the calculated load inertia ratio.
 Mechanical inertia reference value (%):
Load/Motor
Without load
With load
Zero Speed at Start-up Bandwidth
Low Speed Bandwidth
High Speed Bandwidth
Zero Speed at Stop Bandwidth
Settings
 When speed tracking is not ideal, use these parameters to adjust based on the corresponding
frequency bandwidth.
IM Mechanical Brake Release Delay Time / PM Position Control Delay
Time
Settings 0.000–2.000 sec.
 For IM control, when the drive runs and after Pr.13-42 delay time, the mechanical brake release
contact is ON.
 For PM control, the mechanical brake releases, and Pr.13-42 is used as PM position control
delay time.
Mechanical Brake Engage Delay Time
Settings 0.000–2.000 sec.
 When the drive stops and after Pr.13-43 delay time, the mechanical brake release contact is
OFF.
 This function needs to work with DC brake.
