Status and control word in detail
SPX ADVANCED APPLICATION MANUAL
SVCH0203—October 2017 www.eaton.com
B00: FALSE = OFF 1, TRUE = ON 1
OFF 1: Drive will make ramping stop and goes to “Ready to
switch-on”. If drive is in “Switch on Inhibit” state this bit is
used to reset this status.
ON: Voltage connected to drive and/or DC link charged if
drive has the control.
B01: FALSE = Coast stop (OFF 2), TRUE = ON 2
Coast Stop: Drive will make coasting stop and goes to
“Switch-on Inhibit” state
ON 2: No Coast Stop command
B02: FALSE = Quick Stop (OFF 3), TRUE = ON 3
Quick Stop: Drive will make stop function defined by Quick
Stop function parameter.
ON 3: No Quick stop command.
B03: FALSE = Stop Request, TRUE = Start Request
Stop Request: Drive will make stop defined by
stop function.
Start Request: Start Command to the drive.
B04: FALSE = Reset Ramp Generator, TRUE = Enable
Ramp Generator
This bit has priority over B05 and B06 in Control Word.
Reset Ramp Generator: Closed Loop: Ramp generator
is forced to zero, drive will make stop as fast as
possible running against set torque limits or e.g. over
voltage controller.
Enable Ramp Generator: Ramp Generator function is enabled.
To activate Jogging function from fieldbus B04, B05 and
B06 needs to be zero.
B05: FALSE = Freeze Ramp Generator, TRUE = Unfreeze
Ramp Generator
This bit has priority over B06 but not over B05.
Freeze Ramp Generator: Drive will not accept new
reference from Fieldbus, drive remain in same speed.
Unfreeze Ramp Generator: Drive will follower reference
from Fieldbus.
To activate Jogging function from fieldbus B04, B05 and
B06 needs to be zero.
B06: FALSE = Disable Set point, TRUE = Enable Set point
This bit has lowers priority compared to B04 and B05.
Disable Set point: Reference (FW:FreqRef1) is forced to
zero, drive will ramp to zero speed
Enable Set point: Drive will follow reference.
To activate Jogging function from fieldbus B04, B05 and
B06 needs to be zero.
B07: FALSE = No significance, TRUE = Fault Acknowledge
Fault Acknowledge: The group signal is acknowledged with
a positive edge; the drive reaction to a fault depends on
the type of fault (refer to “alarm handling in Appendix A.8).
If the fault reaction has isolated the voltage, the drive then
goes into the “Switching On Inhibited” condition.
8.2.3.1 Jogging function
I/O Jogging Command: Jogging function will start the drive
to reference without additional start command regardless of
control place when given from IO. Jogging function requires
enabling from digital input before command is accepted.
Inching is also disabled if there is start command active
from active control place. If both inching references are
active at the same time drive will stop.
Fieldbus Jogging Command: Jogging command is activated
by giving normal start command but the ramp control bits
CW.B4, B5 & B6 needs to be zero. Drive needs to be at
zero speed before command is accepted and CW.B4, B5
& B6 are active after drive is at zero speed when jogging
function is stopped. See Figure below.
B08: FALSE = No Function, TRUE = Jogging 1
Inching 1: Drive follows reference set by Jogging Ref 1.
Function needs to separately activated by Aux Control Word
or by digital input Enable Jogging when IO control used
for Jogging.
B09: FALSE = No Function, TRUE = Inching 2
Inching 2: Drive follows reference set by Jogging Ref 2.
Function needs to separately activated by Aux Control Word
or by digital input Enable Jogging when IO control used
for Jogging.
