9.2.7.1 Read request: Querying the heatsink temperature
The heatsink temperature of the controller is to be read.
 Code to be read: C00061
 Heatsink temperature: 43 °C
Byte 1: Service (request)
 Request = 0t110001
bin
– Bit 0 ... 2 = 001
bin
for read request
– Bit 3 = 0 (reserved)
– Bit 4/5 = 01
bin
for 2-byte data length (only relevant for the response telegram)
– Bit 6 = handshake bit (t ≡ status is changed in the response telegram)
– Bit 7 = status bit (only relevant for the response telegram)
Byte 2: Subindex
 Subindex = 0 because code C00061 does not contain any subindices.
Bytes 3 + 4: Index
 Index = 24575 - code number = 24575 - 61 = 24514 = 0x5FC2
– Byte 3 (high byte) = 0x5F
– Byte 4 (low byte) = 0xC2
Bytes 5 ... 8: Data
 The response telegram contains the value of code C00061:
– Data 3 + 4 = 43 [°C] x 1 (internal factor) = 43 = 0x002B
Result:
 Request telegram from master to drive:
