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.
10.2.3.1 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.
