0
0
ERR
An error occurred
0: no error
1: Fault
Indicates whether there is a variable frequency drive/variable
speed starter fault. If this is the case, the device will respond
as configured in PNU 362.0.
1
RUN
Operation (output enabled)
0: Error present or no start signal generated
1: A start signal is present and there is no error.
The output of the variable frequency drive/variable speed
starter is active.
2
RDY
Ready, switched on
0: Not switched on; mains voltage is missing or there is an
error
1: Switched on and no error present
Indicates whether the variable frequency drive/variable speed
starter is switched on (mains side).
3
FWD/REV
Direction of rotation
0: Clockwise rotating field (FWD)
1: Anticlockwise rotating field (REV)
4
f_Limit
Actual speed is greater than the signalling threshold
0: Actual speed is less than or equal to the signaling threshold
1: Actual speed is greater than the signalling threshold
If the actual speed is greater than the value set on relay output
1, the value will be 1. Otherwise, it will be 0.
5
I > Limit
Overcurrent
The bit will have a value of 1 if the condition below is met;
otherwise, it will have a value of 0.
The motor current is greater than the limit value – comparable
to the relay function if P-18 = 5 (DC1) or P-51 (DE11).
6
f = f-ref
Operation at reference frequency in stationary state
0: Ref. frequency not reached
1: Ref. Frequency reached
7
Remote Input 1
Status of digital input 3
0: No voltage at DI3
1: 24 V DC present at DI3
￫
Bits 8 to 15 are not used.
