ADP high-speed output special adapter (hereinafter called high-speed
output special adapter) is a special adapter dedicated to FX3U Series PLC. It outputs
pulse signals of a differential line driver system for applicable Servo Amplifiers (or Drive
Unit) of an AC servomotor or stepper motor.
Up to two units of this special adapter can be connected to the main unit per system.
→ → → → For system configuration, refer to the FX3U Series
User's Manual - Hardware Edition.
1.1 Incorporated Items
Check if the following product and items are included in the package:
1.2 Output Number and Signal
When power is turned on, the output numbers and signals of the high-speed output
special adapters are allocated as shown in the table below in the order of it near the
main unit.
*1 A function extension board is required to use the high-speed I/O special adapter
together with a communication/analog special adapter.
→ → → → For system configuration, refer to the FX3U Series
User's Manual - Hardware Edition.
Caution
1)When a high-speed output adapter is connected, the same output number is
allocated to both the main unit and this adapter. Use either output terminal and do
not wire to the unused output terminal.
The outputs from the high-speed output special adapter and main unit are
operated as below:
*1 The output frequency of transistor outputs in the main unit is a maximum of
100kHz. If the load is operated using pulses at a frequency more than 100kHz,
PLC may be damaged.
*2 PWM instruction has not supported the relay output for the reasons of the
response delay of the output, chattering of contact, the contact life, etc.
