Verify Motor Speed, KEB/TorqMAX
If the car is not running at inspection speed as verified using a hand-held tachometer:
• Check the inspection speed setting (F7:155, page 4-135)
• Check F7:141 Profile Scaling at 100%.
• Check motor speed is properly set, KEB LF.11.
• Verify traction sheave diameter and setting, KEB LF.21.
• Verify Closed Loop control setting KEB LF.30 is set to 2 (closed loop)
• Check F7:148 Hoist motor speed is properly set (increase = faster speed; decrease = slower
speed). This value reflects the motor RPM at contract speed.
• If the ELGO landing system is installed, access the controller MPU, ELGO F3 menu and
check that it shows the correct inspection speed. If not, set LF.22 to a value between 125%
and 150% of LF.25. Adjust F7:148 Motor RPM to modify inspection speed.
KEB: Drive parameters LF.20 Contract Speed, LF.21 Sheave diameter, and LF.11 Motor RPM
determine the drive’s Estimated Gear Ratio, LF.25. If problems reaching speed persist, make
LF.22 = 150% of LF.25 value.
Verify Motor Speed, Magnetek
If the car is not running at inspection speed as verified using a hand-held tachometer:
1. While running on Inspection, verify that the Speed Command on the drive D1 Elevator
Data menu is equal to the controller requested F7, 155, Inspection Speed (Normal).
2. On the controller F3 menu, select the car speed display.
3. While running on Inspection, verify the actual speed via the controller LCD or a hand-
held tachometer (controller LCD preferred). Adjust Contract Mtr Spd on the drive A1
Drive Menu if the speed is not correct (higher RPM for increased speed).
4. When the elevator is running at the correct speed, verify that the controller F5, MPI-C
Diagnostic menu, address 17, Raw Speed Feedback, displays the correct value. If not,
adjust controller V7, 148, Hoist Motor Speed (lower RPM = increased speed).
