stopped using this stop mode.
3
Run
1
Proceed to
OPERATION ENABLED
.
Note:
Run enable signal must be active. If the drive is set to receive

Inhibit operation. Proceed to
OPERATION INHIBITED
.
4
Ramp out zero
1
Normal operation. Proceed to
RAMP FUNCTION GENERATOR:
OUTPUT ENABLED
.
0
Force Ramp function generator output to zero. The drive will
immediately decelerate to zero speed (observing the torque limits).
5
Ramp hold
1
Enable ramp function.
Proceed to
RAMP FUNCTION GENERATOR: ACCELERATOR
ENABLED
.
0
Halt ramping (Ramp Function Generator output held).
6
Ramp in zero
1
Normal operation. Proceed to
OPERATING
.
Note:
This bit is effective only if the fieldbus interface is set as the
source for this signal by drive parameters.
0
Force Ramp function generator input to zero.
7
Reset
0=>1
Fault reset if an active fault exists. Proceed to
SWITCH-ON
INHIBITED
.
Note:
This bit is effective only if the fieldbus interface is set as the
source of the reset signal by drive parameters.
0
Continue normal operation.
8
Inching 1
1
Accelerate to inching (jogging) setpoint 1.
Notes:
• Bits 4…6 must be 0.
• See also section
(page
0
Inching (jogging) 1 disabled.
9
Inching 2
1
Accelerate to inching (jogging) setpoint 2.

0
Control word and reference not getting through to the drive, except
for bits 0…2.
11
Ext ctrl loc
1
Select External Control Location EXT2. Effective if control location is
parameterized to be selected from fieldbus.
