33-8* Global Parameters
33-80 Activated Program Number
PRGPAR
Range
-1 – 127 ¾ -1
–1 = Program number is not activated, i.e.
no program to start after autoexec
0 – 127 = activated program number is started
after power up (and autoexec)
The power-up state will be defined with p. 33-81.
Function
With PRGPAR it is possible to set which program
should be started after the conclusion of a program
executed via
Autostart (auto identification). This
parameter can also be changed and stored with
other programs or via the display.
If no program number is activated and no input for
the program start I_FUNCTION_n [13] or [14] is
set, then the program with auto identification will
be started.
NB!:
If no autostart program is defined then it
is not possible to start a program via
PRGPAR; this always requires a
terminated autostart program.
33-81 Power-up State
Power-up-State
Option
Motor off [0]
¾ Motor on [1]
Function
Controller state after power-up can be defined.
Select Motor off [0] if the motor must remain un-
controlled (FC 300 is coasted) after power-up.
FC 300 and position control must be enabled with
the MOTOR ON command before movement can be
started.
Select Motor on [1] if the motor must be controlled
after power-up, positioning controller is active and
keeps the actual position until another control
command is given.
33-82 Drive Status Monitoring
STATUSMONITORING
Option
Off [0]
¾ On [1]
Function
Enable/disable monitoring of FC 300 status while
position control from MCO 305 is active.
Select Off [0] if monitoring must be disabled i.e.
MCO 305 will try to control the motor independent
of FC 300 status. Will normally lead to a position
error (error 108) when trying to start a movement
while FC 300 is not enabled.
Select On [1] if monitoring must be enabled. Error
113 will be activated if FC 300 is not enabled (e.g.
trip) while MCO 305 is in the MOTOR ON state
(position control).
33-83 Behavior after Error
ERRCOND
Option
¾ Coast [0]
Coast and brake [1]
Controlled stop [2]
Controlled stop and brake [3]
Jumps to error routine without
automatic MOTOR OFF
[5]
Function
0 = Standard, i.e. drive moves in COASTING,
control loop is interrupted.
1 = Like [0], but brake output (if defined) is
activated.
2 = Motor stop with maximum deceleration (stop
ramp), subsequently standstill control.
3 = Like [2], brake output (if defined) is activated
in addition, but only after MOTOR STOP.
All other activities such as MOTOR OFF etc.
must be set in the ON_ERROR routine.
5 = Jumps to the error routine, but the control will
not switch off automatically. This can or must
be initiated in the application program with a
MOTOR OFF in the error routine.
NB!:
A brake output has to be defined in
parameter 33-63 through 33-70,
O_FUNCTION_n Option 5 and 6.
