Set an analog input terminal for torque compensation (H3- = 14) and proceed with the steps below.
Procedure for Load Condition 1 (S3-27, S3-29)
1. Make sure the drive is wired properly. For instructions, refer to Standard Connection Diagram on page 25 .
2. Set the speed reference to 0%.
3. Apply no weight to the elevator car.
4. Note the value of the analog input monitor for the load signal input is connected to (U1-13 for terminal A1, U1-14
for terminal A2).
5. Provide an elevator Up or Down command, using Inspection Operation or normal operation mode. The car
should be held in place when the brake releases.
6. Note the drives internal torque reference monitor U1-09.
7. Stop the drive.
8. Set the value noted in step 4 to parameter S3-29. Set the value noted in step 6 to parameter S3-27.
Procedure for Load Condition 2 (S3-28, S3-30)
1. Set the speed reference to 0%.
2. Apply load to the car has much as possible (at least 50% of the maximum weight).
3. Note the value of the analog input monitor for the load signal input connected to (U1-13 for terminal A1, U1-14 for
terminal A2).
4. Provide an elevator Up or Down command, using Inspection Operation or normal operation mode. The car
should be held in place when the brake releases.
5. Note the drives internal torque reference monitor U1-09.
6. Stop the drive.
7. Set the value noted in step 3 to parameter S3-30. Set the value noted in step 5 to parameter S3-28.
Figure 47 shows the Torque Compensation at Start settings with parameters S3-27 to S3-30.
The solid line in Figure 47 indicates the torque compensation at start when the elevator moves up or down.

Note: PRG: 7015 or earlier will apply a limit at 0 V torque compensation input value.
PRG: 7016 or later have no torque compensation limit when adding negative voltage to analog input voltage (see Figure 47 ).
