Note
No detection of a change of direction with the aid of p1820 or p1821
If the direction of rotation is reversed via p1820 or p1821, then safe monitoring is still possible:
However, in this case, the setpoint limitation r9733 is calculated with the wrong direction of
rotation. A reversal of the rotational direction with p1820 or p1821 therefore does not make
sense.
Restart after pulse cancellation for p9509.8 = 0
If the drive has been switched off via OFF1/OFF2/STO etc., the following steps need to be
carried out before a restart can be performed:
1. Case
State after switching on
SDI selected
STO selected
Pulse suppression active
Deselect STO
The drive enable must be issued within 5 seconds via a positive edge at OFF1, otherwise
STO is reactivated.
2. Case
Situation
Traversing to standstill with SDI selected
Initiate OFF1
Pulses are canceled; internal selection STO becomes active
Select STO
Deselect STO
STO activated internally via pulse suppression: This activation must be undone by se‐
lecting/deselecting STO.
The drive enable must be issued within 5 seconds via a positive edge at OFF1, otherwise
STO is reactivated.
3. Case
Situation
Traversing to standstill with SDI selected
Initiate OFF1
Pulses are canceled; internal selection STO becomes active
Deselect SDI
STO activated internally via pulse suppression: This activation must be undone by de‐
selecting SDI.
Select SDI
The drive enable must be issued within 5 seconds via a positive edge at OFF1, otherwise
STO is reactivated.
