 PT100 operation

(1) Use AVI, AUI or ACI(set to 0-10V) for analog voltage input and select PT100 mode.

(2) Choose one of the analog voltage input type: (a)AVI (Pr.03-00=11), (b) AUI (Pr.03-02=11), or

(3) When using ACI as analog voltage input, set Pr.03-01=11 and Pr.03-29=1. Then switch SW2

to 0-10V on the I/O control terminal block.

(4) Set Pr.03-23=23 and AFM2 to constant current output. Switch AFM2 (SW2) to 0-20mA on 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.

(5) Pr.03-33 is for adjusting the constant voltage or constant current of AFM2, the setting range is

0~100.00%.

(6) There are two types of action level for PT100. The diagram of PT protecting action is shown

as below:

Level 2 06-57=

Setting range 0.000 10.000V

Factory setting: 7.000V

: ~

Level 1 06-56=

Setting range: 0.000 10.000V

Factory setting: 5.000V

Frequency

Command

When voltage of PT100 reaches level 1,

the frequency command goes back to Pr.06-58.

the drive passed the delay time set at Pr06-59 ,

When voltage of PT100 reaches level 2, the drive activate

protecting action by following the setting of Pr.06-29.
