9.3.4 Switching between positioning and synchronous operation
The "Free running" function makes it possible for the drives to run separately at a con-
trolled speed. However, when this function is activated, the drive cannot move to a spec-
ified position using position control.
To perform this function, the operating mode Positioning (IPOS
plus®
) is required.
In the following sample program, the system can switch between the operating modes
Synchronous operation and Positioning via input terminal DI12.
In this context, note the following condition:
The following sample program looks at a switchover between the operating modes CFC
& IPOS and CFC & SYNC with SETSYS.
The following settings apply (terminal function via the IPOS
plus®
program determines
the parameter settings for all used inputs at the IPOS input):
• DI10 = 0 no free-running
• DI10 = 1 Free running, if operating mode CFC & SYNC is set
• DI11 = 0 no function
• DI11 = 1 Set DRS zero point (pulse)
• DI12 = 1 Positioning, operating mode CFC & IPOS
• DI12 = 0 Synchronous operation, operating mode CFC & SYNC
The operating modes can be changed using the command
_SetSys(SS_OPMODE, H)
In which the value of the H variable has the following meaning:
INFORMATION
The system can only change from synchronous operation to positioning in the
operating modes CFC or SERVO when the drive is in operation.
For the VFC operating modes, MOVIDRIVE
®
must be in the status Controller inhibit.
SS_OPMODE: Sets the operating mode
H = 11: Operating mode CFC (speed control)
H = 12: Operating mode CFC & torque control
H = 13: Operating mode CFC & IPOS (positioning)
H = 14: Operating mode CFC & synchronous running (DRS11A)
H = 16: Operating mode SERVO (speed control)
H = 17: Operating mode SERVO & torque control
H = 18: Operating mode SERVO & IPOS (positioning)
H = 19: Operating mode SERVO & synchronous running (DRS11A)
