Delta C2000 Series User Manual page 376

When using ACI as analog voltage input, set Pr.03-01=11 and Pr.03-29=1. Then switch
(3)
SW2 to 0-10V on the I/O control terminal block.
Set Pr.03-23=23 and AFM2 to constant current output. Switch AFM2 (SW2) to 0-20mA on
(4)
the I/O control terminal block and set constant current output to 9mA by setting Pr.03-33=45.
The AFM2 constant output current is 20mA * 45% = 9mA.
Pr.03-33 is for adjusting the constant voltage or constant current of AFM2, the setting range
(5)
is 0~100.00%.
There are two types of action level for PT100. The diagram of PT protecting action is shown

When Pr.06-58=0.00Hz, PT100 function is disabled.
Example:
A PT100 is installed to the drive. If motor temperature reaches 135
will decrease motor frequency to the setting of Pr.06-58. Motor will operate at this frequency
(Pr.06-58) till the motor temperature decreases to 135 (275°F) or lower. If motor temperature
exceeds 150 (302°F), the motor will decelerate to stop and outputs an 'OH3' warning.
Set up process:
1. Switch AFM2 (SW2) to 0-20mA on the I/O control terminal block. (Refer to Figure 1, PT100
wiring diagram)
2. Wiring (Refer to Figure 1, PT100 wiring diagram):
Connect external terminal AFM2 to (+)
Connect external terminal ACM to (-)
Connect external terminals AFM2 and AVI to short-circuit
Chapter 12 Description of Parameter Settings
When voltage of PT 100 reaches level 1,
the drive passed the delay time set at Pr06-59 ,
the frequency command goes back to Pr.06-58.
When voltage of PT 100 reaches level 2, the drive activate
protecting action by following the setting of Pr.06-29.
