Drive Monitoring
The network can always read drive parameters as long as the Modbus communications
are enabled (i.e. P400 = 2) and configured properly (see P410-412).
7.2
Drive Programming and Control
Network Control must be enabled for the network to program drive parameters or take
control of an actual drive. This is done by …
1) Setting P121…P123 equal to 09 (NET ENABLE) and asserting the corresponding
TB-13x terminal
2) Setting P100 to 00, 01, 03 or 04. Network control cannot be enabled when P100 is
set to 02 (REMOTE KEYPAD ONLY) or 05 (TERMINAL STRIP/REMOTE KEYPAD).
Once network control is enabled, the drive must unlock controls and/or parameters in
order to write to any of the drive registers.
7.3
Unlocking & Locking of Drive Controls and Parameters
Writing to Register #48 (Unlock Controls) with a value of 0 will unlock write access to the
Drive Control register (#1) only. Write commands to any other drive registers will not be
allowed.
Writing to Register #48 (Unlock Controls) with a value equal to the drive’s programming
password (P194) will unlock the Drive Control register (#1) and all other writable drive
registers. This enables the writing of any drive register that is not designated as read-
only.
Note
The factory default password is 225
Writing to Register #49 (Unlock Parameters) with a value equal to the drive’s
programming password (P194) will unlock all writable drive registers EXCEPT for the
Drive Control register (#1). This enables the writing of any drive register that is not
designated as read-only, except for Register #1.
Once write access to the drive registers has been unlocked, it will remain unlocked until
any of the following conditions occur …
• Register #1 (Drive Control) is written with bit 1 (Lock Security) set
• A network watchdog time-out occurs (see Sections 7.4 and 7.5)
• The TB-13x terminal assigned to NETWORK ENABLE is de-asserted or is assigned
to a function other than NETWORK ENABLE.
Writing to Register #1 (Drive Control) with bit 1 (Lock Security) set will lock both Drive
Controls and Parameters, disabling the watchdog timer and preventing any further writing
to drive registers (other than #48 and #49).
