Chapter 12 Description of Parameter SettingsCT2000 Series
When using ACI as analog voltage input, set Pr.03-01=11 and Pr.03-29=1. Then switch SW2
(3)
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 the
(4)
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 is
(5)
0~100.00%.
There are two types of action level for PT100. The diagram of PT protecting action is shown

as below:

 When Pr.06-58=0.00Hz, PT100 function is disabled.
Example:
A PT100 is installed to the drive. If motor temperature reach 135℃ (275°F) or higher, the drive 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 raise beyond
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
3. Set Pr.03-00=11 or Pr.03-23=23 or Pr.03-33=45%(9mA)
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.
