MP_EPIV_R6_Parameter

MP_EPIV_R6_Parameter 1:

This function block is used to parameterize drives of series EP..R-R6+BAC.

MP_Address is used to specify the MP-Bus device with which the function block is to communicate. bStart activates communication with the MP-Bus device. bBusy indicates that the function block is active. bError is used to indicate an error in communication with the drive. The type of the error can be read with iErrorID.

Description

MP_Address

USINT

MP-Bus address of the slave.

bStart

BOOL

A positive edge starts the function block. If this remains continuously TRUE, the function block will be activated cyclically with a period specified by the time in TMPolling.

bRead_Write

BOOL

If FALSE then READ only; if TRUE then READ and WRITE.

strDataKL6771

DataKL6771

The data structure with which the KL6771() function block must be linked.

nUnitSelection_Write

E_MP_EP_R_R6_UnitSel

Scaling for rAbsoluteFlow_UnitSel

bControlMode_Write

BOOL

FALSE: position-controlled, TRUE: flow-controlled.

rVmaxSeq1_Write

LREAL

0...100 %.

rVmaxSeq2_Write

LREAL

0...100 %.

Name

Type

Description

bBusy

BOOL

This bit is set for as long as the function block is active.

bError

BOOL

This output goes TRUE as soon as an error occurs. This error is described via the iErrorId variable.

iErrorId

MP_ERROR

This output outputs an error code in the event of an error. bError goes TRUE at the same time.

strMP_Serial_Number

MP_Serial_Number

Structure for the serial number

nUnitSelection_Read

E_MP_EP_R_R6_UnitSel

Setting the scaling

bControlMode_Read

BOOL

FALSE: position-controlled, TRUE: flow-controlled.

rVmaxSeq1_Read

LREAL

Maximum sequence speed 1 in % (0...100 %).

rVmaxSeq2_Read

LREAL

Maximum sequence speed 2 in % (0...100 %).

rAbsVnom_InitSel

LREAL

Nominal volume (see rAbsoluteFlow_UnitSel).

rAbsVnom_l_h

LREAL

Nominal volume in l/h (0...4294967295).

rAbsVnom_gpm

LREAL

Nominal volume in gpm (0...4294967295).
