Selection (Value)
Default: Read Only
Range: 0 to 150%
Auxiliary cooling fan age. Displays the age of the auxiliary cooling fan
as a percentage of its estimated lifetime. The estimate is based on
the duty, operating conditions and other operating parameters of the
fan. When the counter reaches 100%, a warning (A8C0 Fan service
counter) is generated.
Can be reset from the control panel by keeping Reset depressed for
over 3 seconds.
Default: Read Only
Range: 0 - 15
1 - Proceed to READY TO OPERATE.
0 - Stop along currently active deceleration ramp. Proceed to OFF1
0 (Off1 control)
ACTIVE; proceed to READY TO SWITCH ON unless other
interlocks (OFF2, OFF3) are active.
1 - Continue operation (OFF2 inactive).
1 (Off2 control)
0 - Emergency OFF, coast to a stop.
Proceed to OFF2 ACTIVE, proceed to SWITCH-ON INHIBITED.
1 - Continue operation (OFF3 inactive).
2 (Off3 control)
0 - Emergency stop, stop within time defined by drive parameter.
Proceed to OFF3 ACTIVE; proceed to SWITCH-ON INHIBITED.
1 - Proceed to OPERATION ENABLED.
Note: Run enable signal must be active; see drive documentation.
3 (Run)
If the drive is set to receive the Run enable signal from the
fieldbus, this bit activates the signal.
0 - Inhibit operation. Proceed to OPERATION INHIBITED.
1 - Normal operation. Proceed to RAMP FUNCTION GENERATOR:
OUTPUT ENABLED.
4 (Ramp out zero)
0 - Force Ramp function generator output to zero. The drive will
immediately decelerate to zero speed (observing the torque limits).
1 - Enable ramp function. Proceed to RAMP FUNCTION GENERATOR:
5 (Ramp hold)
ACCELERATOR ENABLED.
0 - Halt ramping (Ramp Function Generator output held).
1 - Normal operation. Proceed to OPERATING.
Note: This bit is effective only if the fieldbus interface is set as the
6 (Ramp in zero)
source for this signal by drive parameters.
0 - Force Ramp function generator input to zero.
0=>1 - Fault reset if an active fault exists. Proceed to SWITCH-ON
7 (Reset)
0 - Continue normal operation.
1 - Accelerate to inching (jogging) setpoint 1.
8 (Inching 1)
Notes: Bits 4...6 must be 0.
0 - Inching (jogging) 1 disabled.
1 - Accelerate to inching (jogging) setpoint 2. See notes at bit 8.
9 (Inching 2)
0 - Inching (jogging) 2 disabled.
