6.
Observe the SJ300EL torque monitor by setting keypad display to monitor parameter
D012
. Display is in percent of full load torque. Adjust the counterweight so that the torque
monitor reads less than 15% of rated torque.
7.
Adjust
H033
(I
0
) until the torque monitor reading (parameter
D012
) is less than 5% of
rated torque.
8.
Make sure it is safe to run the car at contract (maximum design) speed.
9.
Run the car at contract speed fully loaded and at minimum load, in both directions. Be
sure the torque and current never exceed 150% of the drive full load ratings. Confirm this
by monitoring parameters
D002
for current in amperes, and
D012
for torque in percent of
full load torque.
10.
Check for any unstable or irregular elevator motion. Manually adjust the motor
parameters if necessary.
