5.3.5 Example
This example shows how to use PPO type 1 to change the ramp-up time (par. F-07 Accel Time 1) to 10 seconds and to command a start and speed reference of
50%.
Frequency converter parameter settings:
par. O-50 Coasting Select: Bus
par. O-10 Control Word Profile: PROFIdrive profile
5.3.6 PCV
PCA Parameter Characteristics
PCA part (byte 1-2).
The RC part tells what the PCV part must be used for. The functions available appear from the table, see PCA handling.
When a parameter is to be changed, choose value 2 or 3. In this example 3 is chosen, because par. F-07 Accel Time 1 covers a long word (32 bits).
par. F-07 Accel Time 1 = 155 hex: In this example byte 1 and 2 are set to 3155.
IND (bytes 3-4):
Used when reading/changing parameters with sub-index, for example par. PB-15 PCD Write Configuration. In the example bytes 3 and 4 are set to 00 Hex.
PVA (bytes 5-8):
The data value of par. F-07 Accel Time 1 must be changed to 10.00 seconds. The value transmitted must be 1000, because the conversion index for par.
F-07 Accel Time 1 is 2. This means that the value received by the frequency converter is divided by 100, such that the frequency converter perceives 1000 as 10.00.
Bytes 5-8 = 1000 = 03E8 Hex. See Object and Data types supported.
5.3.7 PCD
Control word (CTW) according to PROFIdrive profile:
Control words consist of 16 bits. The meaning of the each bit is explained in the section Control word and Status word. The following bit pattern sets all necessary
start commands:
0000 0100 0111 1111 = 047F Hex.*
0000 0100 0111 1110 = 047E Hex.*
0000 0100 0111 1111 = 047F Hex.
Quick stop: 0000 0100 0110 1111 = 046F Hex.
Stop: 0000 0100 0011 1111 = 043F Hex.
NB!
* For restart after power up: Bit 1 and 2 of the CTW must be set to 1 and bit 0 toggled from 0 to 1.
