Rockwell Automation 1336T Master/Slave Parallel AC Drv - Manual (Page 33)

1336 FORCE-5.19 – August, 2000
Startup 3-15
2. Start the Slave Drive followed by starting the Master Drive.
The test is complete when P256 resets to zero.
3. Save in EEPROM, the measured value for Leakage Inductance
can be viewed in parameter 237 (Lsigma Tune).
4. Repeat test to check validity.
Id Measurement Test:
1. Set Parameter 256 [Autotun Diag Sel] to a value of 16.
2. Start the Slave Drive followed by starting the Master Drive.
Motor will accelerate toward autotune speed (typically this
should occur three separate times). Parameters 240-248 will be
updated.
3. The test is complete when Parameter 256 resets to 0.
4. Save in EEPROM, the measured value for Id is in P238 [Base
Flux Cur].
5. Repeat to check validity.
Update Torque Block Gains:
1. Set Parameter 256 [Autotun Diag Sel] to a value of 32.
2. Start the Slave Drive followed by starting the Master Drive.
Motor will NOT rotate during this test.
3. The test is complete when Parameter 256 resets to 0.
4. Set Parameter 244[Vqe Max] = Parameter 242 [Base Flux
Volt].
5. Set the value for Parameter 243 [Vde Max] based on the
following table:
6. Save to EEPROM/BRAM.
Motor Inertia Test: You must run this test if your drive will be
asked to calculate the velocity regulator gains through autotune.
1. Set Parameter 256 [Autotun Diag Sel] to a value of 64.
2. Start the Slave Drive Followed by Starting the Master Drive.
Motor will accelerate toward autotune speed.
3. The test is complete when Parameter 256 resets to 0.
4. The measured value for motor inertia can be viewed in P234
[Motor Inertia].
Run the motor to base speed. Scope the tach feedback to verify proper
50% duty cycle and a phase shift between signals. Record the motor
base speed data on the data sheet.
IMPORTANT: Reset parameter 91 [Stall Delay] to application
value in Master. Slave Stall Delay may need to be set higher to
prevent nuisance trips. Typically 5.0 sec.
