Figure 5-44: Direction of Motion
Direction of Speed values:
Forward = 0
Reverse = 1
Example:
In this example, the Preset Speeds 6 and 2 are to go in reverse direction and all
others are to move in a forward direction.
As shown in Figure 5-44, each bit has an associated value.
Bit 7 = 64, Bit 6 = 32, Bit 5 = 16, Bit 4 = 8
Bit 3 = 4, Bit 2 = 2 and Bit 1 = 1
Then each direction has a number associated with it as stated below.
Use the number 0 for a Forward direction.
Use the number 1 for a Reverse direction.
With the above information the equation can be solved.
= (0 x 64)+(1 x 32)+(0 x 16)+(0 x 8)+(0 x 4)+(1 x 2)+(0 x 1)
= 0+32+0+0+0+2+0+0
50.45 = 34 for this example
50.45
PLC Forward/Reverse
Motion
Range: 0 to 127 Default: 0
This parameter controls the direction of motion for the multi-
speeds 30.18 to 30.24 during the PLC function.
To generate the setting for this parameter the following
equation must be solved.
= (direction of speed 7 x value of bit 7) + (direction of speed
6 x value of bit 6) + (direction of speed 5 x value of bit 5) +
(direction of speed 4 x value of bit 4) + (direction of speed
3 x value of bit 3) + (direction of speed 2 x value of bit 2) +
(direction of speed 1 x value of bit 1)
