12 Examples for Serial Data Transfer
12.1 Power On
Before power on, ensure that the right baud rate has been selected by jumpers in the plug. After power on and/or restart, the
control needs approx. 2 seconds to be ready for operation. This status is signalled by
bit 5 in status byte 1 .
Group No. Description Bit 7 6 5 4 3 2 1 0
0 02 Status Byte 1 PSYN NPE RDY P01 P02 POE DZE STP
Example: Query for readiness for operation after power on (RTS parameter 2)
Master transmits SOH ADR STX ($30 $32) ENQ
Slave transmits SOH ADR STX ($30 $32 $3D $xx $xx)) ETX BCC
The master recognizes the readiness for operation from bit 5.
12.2 Operation
Example : Sequence of the speed profile belo w.
* = Step
Step 1 Determine speed 1 = 4000 [RPM] Control value A Parameter 10 = 2000 [2 RPM]
