Programming of write jobs
Step
Write job
1.
Define the user data range of the motor starter, i.e. define the location of the user data in the host
system.
2.
Enter the address of the desired parameter in the field ”Index and subindex“ (output data).
3.
Enter parameter value in field ”Data/Error“.
4.
Job/Service = Write job
5.
Check whether index and subindex correspond with the job and whether the job identification is Û 0:
z
If the criteria are fulfilled, the master data in the field “Parameter value” is accepted by the motor
starter.
z
If these criteria are not met, the response identification is negative, i.e. high nibble of byte 1 = 7
hex
In this case the error information can be read out of the entry in the low word.
Example: write parameter
The acceleration time (C0012) for the motor 1 is to be set to T
ir
= 2.5 s.
ƒ
Job identification (high nibble in byte 1)
– Transmit simple parameter value: “1”
ƒ
Code: (low nibble in byte 1 and byte 2)
– C0012: 12 = 0C
hex
ƒ
Lenze subcode (byte 3):
– Subindex = 1
ƒ
Byte 5 ...8: data
– Data 1 to data 4 = 2.5 s x 10000 = 25000 = 00 00 61 A8
