2.3 b: Application
Note:
When you change b5-38 and b5-46, the drive will not automatically convert the parameters in
For example, when you set YA-01 = 70.0 [PSI] and change these parameters:
• b5-46 from 1 [PSI] to 8 [Bar]
• b5-38 from 145.0 to 10.0
The drive changes only the unit setting and YA-01 will be 70.0 [Bar]. When the setpoint value after you change b5-38 and b5-46 is more than
b5-38, the drive internally limits the setpoint value to 200% of b5-38. The drive regards the YA-01 setting as 20.0 [Bar].

Full-Scale of the PID Analog Input Signals
The full-scale of the analog signals listed in this table go from b5-71 [Min PID Transducer Scaling] to b5-38 [PID
User Unit Display Scaling].

Note:
When you set b5-71 < 0, the drive appropriately scales the setpoint and feedback values of the drive, but internally limits to 0 when the
reported value from the transducer is negative.
