9.2 Unidrive Sequencing Mode 3
The default sequencing mode for Unidrive is the Wire-Proof PLC Mode.
If PLC Mode is selected (#6.04 = 3), the sequencing bits (#6.30 - #6.32)
have slightly different functions.
Control
Word
Parameter Sequencing Bit PLC Mode
(#6.04 = 3)
b0 #6.15 Enable Enable
b1 #6.30 0 Run
b2 #6.31 1 Jog
b3 #6.32 2 Reverse
ENABLE the display will show "Inh" when set at 0, and depends on
#6.30 and #6.32 when set to 1. Setting #6.15 to 0 overrides
#6.30 and #6.32, and immediately disables the Unidrive.
The motor will coast to rest if it is running when the Unidrive
is disabled.
JOG the jog bit must be set, along with the appropriate run and
direction signals.
To reset the Unidrive using the Profibus-DP network, use the non-cyclic
channel to set #10.38 to 100. The Unidrive will clear #10.38 back to 0
and reset. (See Unidrive manual for more information.)
Some example control word values for the Unidrive are given in the
tables below.
