With
status measurement
you get information about limit violations.
n
The limit values can be defined via the parametrization.
n
The
status measurement
is refreshed together with the other measurement values, as
soon as the DS-ID is incremented.
n
Set bits of
status measurement
remain set as long as they are acknowledged by
Chapter 3.27.7.2.5 ‘CMD Frame’ on page 327
n
Byte order: high byte, low byte (big endian)
Byte
Description
0
0: de-activated, 1: activated
n
Bit 0: Voltage at phase L2 below limit value (L2: VRMS_MIN)
n
Bit 1: Voltage at phase L3 below limit value (L3: VRMS_MIN)
n
Bit 2: Voltage at phase L1 above limit value (L1: VRMS_MAX)
n
Bit 3: Voltage at phase L2 above limit value (L2: VRMS_MAX)
n
Bit 4: Voltage at phase L3 above limit value (L3: VRMS_MAX)
n
Bit 5: Temperature above limit value (T_MAX)
n
Bit 6: Frequency below limit value (F_MIN)
n
Bit 7: Temperature above limit value (T_MAX)
1
0: de-activated, 1: activated
n
Bit 0
–
0: deleted via CMD Frame (0x04)
–
1: if there was a RESET of the module. This happens after PowerON.
n
Bit 1: Current at phase L1 above limit value (L1: IRMS_MAX)
n
Bit 2: Current at phase L2 above limit value (L2: IRMS_MAX)
n
Bit 3: Current at phase L3 above limit value (L3: IRMS_MAX)
n
Bit 4: Efficiency cos
j
phase L1 below limit value (L1: PF_MIN)
n
Bit 5: Efficiency cos
j
phase L2 below limit value (L2: PF_MIN)
n
Bit 6: Efficiency cos
j
phase L3 below limit value (L3: PF_MIN)
n
Bit 7: Voltage at phase L1 below limit value (L1: VRMS_MIN)

Process data communication
During runtime the communication with the module happens via telegrams in the process
image. Here you have the following possibilities:
n
Read measured value
n
Define Frame with measurands
n
Read Frame with measured values
n
Send control command
Data type
