Example 6
•
P255 [Anlg In Type], Bit 0 = “0” (Voltage)
•
P545 [Spd Ref A Sel] = “Analog In 1”
•
P547 [Spd Ref A AnlgHi] = 60 Hz
•
P548 [Spd Ref A AnlgLo] = 0 Hz
•
P61 [Anlg In1 Hi] = 5V
•
P62 [Anlg In1 Lo] = 0V
This configuration is used when the input signal is 0…5V. Here, minimum input
(0V) represents 0 Hz and maximum input (5V) represents 60 Hz. This provides
full scale operation from a 0…5V source.
Example 7
•
P255 [Anlg In Type], Bit 0 = “0” (Voltage)
•
P675 [Trq Ref A Sel] = “Analog In 1”
•
P677 [Trq Ref A AnlgHi] = 200%
•
P678 [Trq Ref A AnlgLo] = 0%
This configuration is used when the input signal is 0…10V. The minimum input
of 0V represents a torque reference of 0% and maximum input of 10V represents
a torque reference of 200%.
