PT100
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
3. Set Pr.03-00=11 or Pr.03-23=23 or Pr.03-33=45%(9mA)
4. Refer to RTD temperature and resistance comparison table
Temperature=135 , resistance=151.71 ; Input current: 9mA, Voltage: approximately: 1.37Vdc
Temperature=150 , resistance=157.33 ; Input current:9mA, Voltage: approximately: 1.42Vdc
Chapter 12 Description of Parameter Settings C2000 Series
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.
