Rated output B axis (Note 1): 0.2kw.
Rated output C axis (Note 1): 0.2kw.
Interface: SSCNET III /H.
Note the 1:A axis, B axis, C axis indicates the name of a type of multi axis servo amplifier axis MR-J4-500B PDF. The C axis represents the 3 axis one type servo amplifier MR-J4-500B
Support SSCNET III /H. 3 axis one type servo amplifier capable of driving 3 servo motors through a single module.
More energy saving, space saving, less wiring, low cost.
Inherited the high performance and high reliability.
Will, as always, adhere to and uphold the excellent quality of MELSERVO MR-J4-500B PDF.
MR-J4 has inherited the excellent design of existing products.
Its essence to its dregs, create advantage and cost effective utilization rate,
Make full use of renewable resources, to create a new product. MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 0.1kw.
Interface type: SSCNET type III fiber communication.
Special features: integrated driver security MR-J4-500B PDF.
Power specification: single phase AC100V.
STO function as a security feature is added to the SSCNET III fiber communication type servo amplifier.
By using the STO function, the electromagnetic contactor used in the past to prevent the motor from accidentally starting is no longer needed.
SS1 functions can be realized by using the MR-J3-D05 security logic unit.
MR-J3-BS uses a full closed loop control system.
Compatibility with MR-J3-B.
MR-J3-BS installation, wiring and connectors are the same as the MR-J3-B, so do not change the existing connection will be easy to MR-J3-B
Change to MR-J3-BS.
Security functions are connected to the CN8 interface through an external security circuit to increase the MR-J3-BS driver security.
Compatible full closed loop control system.
MR-J3-BS has a full closed loop control system version. Drive: MR-H_ACN series built-in positioning function.
Rated output: 22KW.
In servo drive speed closed loop,
Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop.
In order to seek the balance between measurement precision and system cost, incremental photoelectric encoder is generally used as the speed measuring sensor,
The corresponding method is M/T velocity measurement.
Although the M/T measurement method has a certain measurement accuracy and a wide range of measurement,
But this method has its inherent defects,
Mainly includes: the measurement period must be detected at least one complete encoder pulse, liimiting the minimum detectable speed MR-J4-500B datasheet.
2 control system for speed control of the timer switch is difficult to maintain synchronization,
Can not guarantee the accuracy of measurement in the situation where the speed change is largger MR-J4-500B datasheet.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
