Chart 7-8 Incremental encoder PG card with frequency division (MT500-PG-INC2) port definition
In the schematic diagram of the crossover card in Table 7-5, the dial switch indicates bit 0~bit5 of the
frequency division number from right to left, the frequency division range is 0~63, and the frequency
division number is set to 0 and 1 when there is no frequency division.
Frequency division corresponding to a single DIP switch
For example 35 frequency division： 35 = 32+2+1
Just turn the dial switches corresponding to the subscripts 1, 5, and 6 to "ON". Please refer to the
description of MT500-PG-INC1 for encoder wiring of MT500-PG-INC2.

7.3 IO Extension card
 MT500-IOEX1 Extension card
The MT500-IOEX1 expansion card is a multi-function IO expansion card for VFD530 series inverters. It can

expand 4 channels of DI, 2 channels of AI, and 4 channels of DO. Among them, , AI4 can be used as an
ordinary voltage input analog quantity, and can also be used as a temperature detection input of
PT100/PT1000/KTY84-130 (temperature detection is connected to PT and COM).
The terminal definitions of the MT500-IOEX1 expansion card are shown in Table 7-10
