PT100 Level 1 Frequency Protection

Settings 0.00~600.00 Hz
PT100 operation
Use AVI, AUI or ACI(set to 0-10V) for analog voltage input and select PT100 mode.
(1)
Choose one of the anolog voltage input type: (a)AVI (Pr.03-00=11), (b) AUI (Pr.03-02=11), or
(2)
(c) ACI (Pr.03-01=11 and Pr.03-29=1).
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 constanst 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 constang 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 volt age of PT 100 reaches level 1,
t he drive passed t he delay time set at Pr06-59 ,
t he frequency command goes back t o Pr. 06-58.
When voltage of PT 100 reaches level 2, the drive act ivate
protecting act ion by f ollowing t he setting of Pr.06-29.
