Parameter
Switch Description: Switch parameter set procedure command. This procedure command allows the system to switch
parameter sets. The drive switches to the parameter set which is programmed in the parameter set preselection
(parameter 217). This parameter is used with the SERCOS interface. If this parameter is set true, “1”, the active
parameter set will be changed to the selected value in paramter 217.

Parameter
Switch Description: Parameter set preselection. In the SERCOS configuration the desired parameter set of the drive is
selected by means of the parameter set preselection. The switch parameter set procedure command (see
parameter 216) is used to switch parameter sets. If the drive has no switchable parameter sets, it will only accept
parameter set 0. Therefore, parameter set 0 must be available in every drive and will be activated during
initialization. In the analog configuration the binary set code is provided to the drive via the digital input. Changing
the digital input binary value will initiate switching of the parameter set.
Enumerated Bit Pattern:
Structure of parameter set preselection:
Bit 2 – 0:
0 0 0 – parameter set 0
0 0 1 – parameter set 1
0 1 0 – parameter set 2
0 1 1 – parameter set 3
1 0 0 – parameter set 4
1 0 1 – parameter set 5
1 1 0 – parameter set 6
1 1 1 – parameter set 7
(all other bits are reserved)
Bit 2 of parameter 217 is linked to Digital Input 5. In addition to being used to select the parameter set, if
Digital Input 5 is true, +24V dc, the high winding will be selected for a dual wound motor and the “High Winding
Enable” linkable variable (parameter 526) will be true. In the Spindle configuration this is linked to Relay Output 3
and this relay contact output can be used to close a the high winding motor contactor and open the low winding
contactor. If Digital Input 5 is false, 0V dc, the Low winding will be selected for a dual wound motor and the “Low
Winding Enable” linkable variable (parameter 527) will be true. In the Spindle configuration this is linked to Relay
Output 4 and this relay contact output can be used to close a the low winding motor contactor and open the high
winding contactor.
Bits 1 and 0 of parameter 217 are also linked to Digital Inputs 7 and 9. In dual winding applications this interface
allows for 4 sets of high winding servo parameters and 4 sets of low winding parameters. In single winding
configurations all 8 sets of parameters are available and the high and low winding relay outputs can be linked to
other 8720MC event links.
This value can be set via DriveExplorer or the HIM as well.
