The QSP function serves to stop the drive in an adjustable time irrespective of the setpoint
selection.
ƒ
The function can be controlled via the following inputs (OR’d):
– Control word "CAN1In−DctrlCtrl" bit 3 of CAN1In function block
– Control word "AIF1In−DctrlCtrl" bit 3 of AIF1In function block
– C0135/3 (control word for networking via AIF)
ƒ
C0136/1 indicates the control word C0135.
ƒ
The speed is reduced to "0" within the deceleration time set via C0105.
12.17.2
Operation inhibit (DISABLE)
This function sets "Operation inhibit" (DISABLE) in the drive, i.e. the power output stages
are inhibited and all speed/current/position controllers are reset. In the "Operation
inhibit" state, the drive cannot be started with the command "Controller enable".
ƒ
The function can be controlled via the following inputs (OR’d):
– Control word "CAN1In−DctrlCtrl" bit 8 of CAN1_IN function block
– Control word "AIF1In−DctrlCtrl" bit 8 of AIF1_IN function block
– C0135/8 (control word for networking via AIF)
ƒ
C0136/1 indicates the control word C0135.
12.17.3
Controller inhibit (CINH)
This function sets "Controller inhibit" (CINH) in the drive, i.e. the power output stages are
inhibited and all speed/current/position controllers are reset.
ƒ
The function can be controlled via the following inputs (OR’d):
– Terminal X6 (FALSE = controller inhibit)
– Control word "CAN1In−DctrlCtrl" bit 9 of CAN1In function block
– Control word "AIF1In−DctrlCtrl" bit 9 of AIF1In function block
– C0135/9 (control word for networking via AIF)
– Signal "DCTRL−CInh1" and "DCTRL−CInh2" (ANDed, TRUE = set controller inhibit)
ƒ
C0136/1 indicates the control word C0135.
