Field Flux Tuning – This procedure will setup the field flux table
(parameters 677 through 684) and the rated motor field current (parameter
612) based on the actual motor characteristics.
1. Record the value of the field flux reference (Parm. 676).
2. Set the field flux reference and the field economy reference to
100%.
3. Set KI, KP for the CEMF regulator (Params 672, 673), to their
default value.
4. Set Parameter 612, the rated motor field current to
±
50% of the
actual value, from the motor nameplate data.
IMPORTANT: The drive Start command must be true for the entire time
the test is being performed. If a stop command is issued anytime during
the test, the motor will stop and the test will be aborted. Check parameter
624 (maintain start) to determine if the start command is latched or
momentary.
5. Start the drive and run it at the same speed as specified by parameter
699.
6. Select the Field Flux Tune option (Drive Setup/Autotune/Vel
Tune) using the program terminal.
7. The Field Flux tuning will begin. It takes approximately 5 to 60
seconds for the test to complete, at which time the program terminal
will indicate that the test has been completed and the option of
saving this information in EEPROM can be executed.
Application Setup
NOTE: Prior to doing any further application specific programming, the
application parameters 607, 608, 663 and 664 will have to be programmed
for their final value.
There are several parameters associated with the use of the drive for
specific applications. At this point, the basic drive control has been tuned
for simple speed control. If it is desired to operate the drive using one of
the optional functions, refer to Chapter 5 for a description of the
parameters associated with these functions. In addition to set up of the
drive parameters associated with these functions, it is also necessary to
verify correct configuration of the Source to Sink parameters for the
external control device being used to control the drive for the specific
application. Refer to the appropriate adapter board Instruction Manual for
a description of how to use the adapter board and how to interface the
adapter board to the drive to command various drive functions.
Once the drive has been fully tuned and configured:
1. Record the values of all parameters in the Parameter Value Tables
located in Chapter 7.
2. Use the EEPROM mode in the Programming Terminal to save all
parameters in EEPROM.
