2.3
2.3.4 Analog filter setup without MacTalk:
If MacTalk is not used for setting up parameters/registers related to the analog filters it
must be done as follows.
The motor contains a number of registers which can be accessed from various protocols
depending at which options the motor has.
Protocols available are for example Ethernet (EthernetIP, ProfiNet etc.) and CANopen,
Modbus or the MacTalk protocol.
Each field in MacTalk described earlier in this chapter is accessing a register in the motor.
The registers that are relevant for analog filters setup are:
R100 Afzup_WriteBits
When changing values for the analogue input filter parameters, this register is used in
combination with registers 102-106. First, all of the registers 102-106 must be loaded
with the values to be used for one or more analogue input filters. Then the lower eight
bits in this register are set to select which inputs the parameters in registers 102-106
should control. The firmware will detect this and copy the parameter values from regis-
ters 102-106 to internal storage. Once this has been completed, the firmware sets bit 15
in this register to show that registers 102-106 are free to receive new values for pro-
gramming the remaining inputs with other filter parameters. To use the same filtering for
all analogue inputs, this register can be loaded with 255 (hex FF).
R101 Afzup_ReadIndex
This register makes it possible to read back the analogue input filter parameters for 1 an-
alogue input at a time. To select a new input, write a value of 1 to 8 to this register and
wait for bit 15 to be set high. When bit 15 has been set by the firmware, the registers
102-106 have been loaded with the filter parameters currently used by that analogue in-
put.
These registers acts as setup registers for the analogue filters, but also as the read-out of
the actual settings. The setup and read-out procedures are described above.
R102 Afzup_ConfMin
R103 Afzup_ConfMax
R104 Afzup_MaxSlope
R105 Afzup_Filter
The result of the filtered analog inputs can be read in the following registers. They are
not visible in MacTalk, but can be used in an RxP program or monitored through other
interfaces (Ethernet, CANopen, Modbus etc.)
R81-88 Analog_Filtered
The voltage on inputs 1 to 8 after being filtered in firmware. See the Afzup_Filter, page
208 for filter parameters. 5.00V is equal to a value of 4095.
R89-96 Analog Input
The unfiltered voltage on inputs 1 to 8. 5.00V is equal to a value of 4095.
