Running on Machine Room Inspection

Once you are satisfied that the brake is picking properly, then do the following:
1. Auto-tuning for induction motors (see below).
2. Verify car movement (direction) and motor control and troubleshoot if not correct
"Verifying Car Direction and Motor Control (TORQMAX)" on page
3. Verify pattern command vs. drive speed feedback tracking

Auto-tuning for Induction Motors

For best performance with induction motors it is recommended to first perform the auto-tuning
procedure as follows:
1. Make sure that the rated motor power (LF.10), rated motor speed (LF.11), rated motor
current (LF.12), rated motor frequency (LF.13), rated motor voltage (LF.14) and rated
power factor (LF.15) are entered into the drive before you begin. If the power factor is
not on the name plate, use 0.90 as the value.
2. On the Controller > Configuration > Brake > Control tab, record the value of Pick volt-
age, Hold voltage and Relevel voltage. Then set all three voltages = 15.000 to prevent the
brake from picking.
3. On the Controller > Configuration > Pattern tab, set Pattern scaling = 0.000.
4. On the TORQMAX F5 drive keypad, set Drive configuration (LF.03) = S Lrn. This will
start the learn process. The display will change to StArt.
5. With the iBox INSPECTION switch in the INSP position, press and hold the UP and
ENABLE buttons. The motor contactor should pull in and the brake should not pick.
Motor current will begin to flow, an audible noise in the motor will be heard, and the
drive display will change to LS.103.
The drive will measure various parameters in the motor as well as in the drive's own
power stage. During each measurement the display will change to signify what is being
measured. In the event of problems during the measurement phase, the factory can use
the codes to determine what is happening. Continue to press and hold the ENABLE and
ON switches in until the drive dapples done.
6. In the event that the drive cannot complete the measurements, two error messages may
occur:
• FAILd - the drive was not able to begin measurements due to a configuration error.
Consult the factory to resolve.
• FAIL - the measurement sequence was interrupted, e.g., the inspection ENABLE or
UP switch was released prematurely, electrically the motor was not properly con-
nected. Try the measurement again.
