Drive Response
Depending on how the drive is tuned, the amount of lag between the commanded speed and
drive response can vary. As a result, as the drive is adjusted, the Profile Advance parameter
(CONFIG 02 > SYSTEM CONTROL PARAMETERS) will need to be changed as well. Use the
information below along with the information in the figure
Response Adjustment on page 1-54 ,
and the tuning instructions following the figure to make these adjustment.
• If lag delay is insufficient (see Figure 1.18 (b)), the elevator will plow into a landing. The
acceleration and jerk rate during deceleration to a landing will be greater than profile val-
ues indicate.
• If lag delay is excessive (see Figure 1.18 (c)), the elevator will drag into a landing. The
acceleration and jerk rate during deceleration to a landing will be less than profile values
indicate. In addition, a discontinuity in the profile will occur during the transition from
acceleration to deceleration for movement between floors where a stabilized speed (con-
tract speed) is not reached (short runs).
• To adjust lag delay:
• Set drive analog output 1 to output the Speed Command (TORQMAX LA31=3, Mag-
netek C4 submenu > Analog Output 1 > Speed Command).
• Observe the commanded speed on an oscilloscope. Perform one-floor-run movement
and observe the peak acceleration transitioning to peak deceleration as the elevator
reaches its peak speed (below contract speed). This transition should have no vertical
discontinuity (too much lag delay). This transition adjustment is only valid when the
elevator is unable to reach contract speed for the profile under normal operation.
Adjust lag delay until the vertical discontinuity is eliminated.
• TORQMAX/KEB: Generally, the Profile Advance (CONFIG 02 > SYSTEM CONTROL
PARAMETERS) will be within 50 to 150 milliseconds (o.05 - 0.15 seconds).
• Magnetek: Generally, the Profile Advance (CONFIG 02 > SYSTEM CONTROL PARAME-
TERS) will be within the following range (in milliseconds):
