AutoMax Network Communication Option Board
When updating the Drop_2 master read registers in the WebPak 3000 drive, the
network synchronization flag must be used with the tune/config input enable flag. If the
updating of the indirect parameter numbers in Drop_2 is not properly synchronized to
the values written in Drop_3, improper values written to parameters may result in
unintended drive operation. The following sections describe the proper sequences for
modifying the Drop_2 and Drop_3 master read values.
7.1.1 Enabling the AutoMax Indirect Parameter Numbers
Step 1.
The tune/config input enable flag must have been cleared for a minimum of
600 msec (Drop_1, register 32, bit 14).
Step 2.
Modify AutoMax Indirect Register numbers (Drop_2, registers 32 to 63) with
the parameter numbers that you wish to write to in the corresponding
Drop_3 register. Parameter number 0 deactivates that particular indirect
register.
Step 3.
Modify the corresponding register values (Drop_3, registers 32 to 63) for the
parameters selected in step 2.
Step 4.
Set the tune/config input enable flag (Drop_1, register 32, bit 14).
Step 5.
Toggle the tune/config update synchronization flag (Drop_1, register 32, bit
15).
Step 6.
Monitor the tune/config update synchronization flag loopback bit in the
Indirect Register Status word (Drop_3, register 32, bit 15) until it equals the
value written in step 4.
7.1.2 Changing the AutoMax Indirect Register Values
Step 1.
Modify the desired register values (Drop_3, registers 32 to63).
Step 2.
Toggle the tune/config update synchronization flag (Drop_1, register 32, bit
15).
Step 3.
Monitor the tune/config update synchronization flag loopback bit in the
Indirect Register Status word (Drop_3, register 32, bit 15) until it equals the
value written in step 4.
7.1.3 Disabling the AutoMax Indirect Registers
Step 1.
Clear the tune/config input enable flag (Drop_1, register 32, bit 14).
Step 2.
Toggle the tune/config update synchronization flag (Drop_1, register 32, bit
15).
Step 3.
Monitor the tune/config update synchronization flag loopback bit in the
Indirect Register Status word (Drop_3, register 32, bit 15) until it equals the
value written in step 4.
