MITSUBISHI FR-F720-2.2K Market price | FR-F720-2.2K Introduction

Cable length: 3.0m.
For QnA/ACPU/ motion controller CPU (A series, extended basis system) and the connection between A7GT-CNB.
Applicable models: GT16, GT15, GT11. Transmission line unit for MELSECNET/MINI (-S3) twisted pair data link.
Loop: twisted pair I/F.
Remote station: light I/F (plastic fiber).
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered FR-F720-2.2K
It can avoid the control logic confusion caused by illegal operations.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc..
MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation. Motor series: low inertia, small capacity.
Using a serial absolute / incremental encoder.
Rated output power: 0.1kw.
Rated speed: 3000rpm.
With the brake: without.
Shaft end: straight shaft.
AC servo motor and brushless DC servo motor in the function of the difference: AC servo is better, because it is a sine wave control, torque ripple small.
DC servo is a trapezoidal wave. DC servo is simple and cheap. Power: 2.2kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed. Does not remove the short circuit chip will lead to overheating of the brake resistor.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table.
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling.
MYS type resistor can be used. But please pay attention to the allowable brake use rate.
Do not remove the terminal P/+ and P1 between the short circuit chip, in addition to connecting the DC reactor.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
