Priority stops

CiA402 profile

In the CiA402 profile, separate or not separate mode:

External stop and fault commands, configured as fixed assignments (LIpp, C1pp, C2pp, C3pp, C4pp), on terminal inputs or control word bits, have priority even if the channel is not active.

Commands, configured as switched assignments (Cd11 ... Cd15), are active if and only if the channel is active.

Fixed assignments are configured by the following values:

Channel	Run on state command		Run on edge command
	[2 wire] (2C)		[3 wire] (3C)
Drive terminals	LI2 ... LI6		LI3 ... LI6
Logic I/O card		LI7 ... LI10
Extended I/O card		LI11 ... LI14
Integrated Modbus		C111 ... C115
CANopen		C211 ... C215
Communication card		C311 ... C315
"Controller Inside" card		C411 ... C415

Cp11 is assigned by default to the reverse direction command [Reverse assign.] (rrS).

At the terminals:

Command	Configuration	= 0	= 1	Value for	State reached from
				starting(1)	5-Operation enabled
Freewheel stop	[Freewheel stop ass.]	Stop	No stop	1	2-Switch on disabled
	(nSt)
Fast stop	[Fast stop assign.] (FSt)	Stop	No stop	1	4-Switched on
DC injection braking	[DC injection assign.]	No braking	Braking	0	5-Operation enabled
	(dCI)
External fault	[External fault ass.] (EtF)	No fault	Fault	0	8-Fault

(1)If the assignment is fixed, the value necessary for starting, even if another channel is active.

In run on edge command, configured by [3 wire] (3C), the stop command (run enable) is assigned by construction to LI1. This command is active even if the terminals are not the active channel.

Via the network:

Command	Configuration	= 0	= 1	Value for	State reached from
				starting(1)	5-Operation enabled
Fast stop	[Fast stop assign.] (FSt)	No stop	Stop	0	4-Switched on
DC injection braking	[DC injection assign.]	No braking	Braking	0	5-Operation enabled
	(dCI)
External fault	[External fault ass.] (EtF)	No fault	Fault	0	8-Fault

(1)If the assignment is fixed, the value necessary for starting, even if another channel is active.

In the CiA402 profile, the freewheel stop command [Freewheel stop ass.] (nSt) cannot be assigned to the control word. Freewheel stop is obtained via the "5-Disable operation" or "Halt" command with the Type of Stop [Type of stop] (Stt) parameter configured to [Freewheel] (nSt).
