MR-J3-70B MRJ370B MITSUBISHI AC Servo SAFETY AMP 700W 200V

Product Details

The Mitsubishi MELSERVO-J3 series general-purpose AC servo has further higher performance and higher functions compared to the current MELSERVO-J2-Super series.The MR-J3-B servo amplifier connects to servo system controller and others via high speed synchronous network and operates by directly reading position data. The rotation speed/direction control of servo motor and the high accuracy positioning are executed with the data from command module. SSCNET equipped by theMR-J3-B servo amplifier greatly improved its communication speed and noise tolerance by adopting optical communication system compared to the current SSCNET. For wiring distance, 50m of the maximum distance between electrodes is also offered.The torque limit with clamping circuit is put on the servo amplifier in order to protect the power transistor of main circuit from the over current caused by rapid acceleration/deceleration or overload. In addition, torque limit value can be changed to desired value with parameter.
As this new series has the USB communication function, a MR Configurator-installed personal computer or the like can be used to perform parameter setting, test operation, status display monitoring, gain adjustment, etc. With real-time auto tuning, you can automatically adjust the servo gains according to the machine.
The MELSERVO-J3 series servo motor is equipped with an absolute position encoder which has the resolution of 262144 pulses/rev to ensure more accurate control as compared to the MELSERVO-J2-Super series. Simply adding a battery to the servo amplifier makes up an absolute position detection system. This makes home position return unnecessary at power-on or alarm occurrence by setting a home position once.

Specifications

Function

Gain search function: Personal computer changes gains automatically and searches for overshoot-free gains in a short time.MR Configurator is necessary for this function.

Slight vibration suppression control: Suppresses vibration of 1 pulse produced at a servo motor stop.

Auto tuning: Automatically adjusts the gain to optimum value if load applied to the servomotor shaft varies. Higher in performance than MR-J2-Super series servo amplifier.

Return converter: Used when the regenerative option cannot provide enough regenerative power.Can be used the 5kW or more servo amplifier.

Regenerative option: Used when the built-in regenerative resistor of the servo amplifier does not have sufficient regenerative capability for the regenerative power generated.

Alarm history clear: Alarm history is cleared.

Output signal (DO)forced output: Output signal can be forced on/off independently of the servo status.Use this function for output signal wiring check, etc.

Test operation mode: JOG operation positioning operation DO forced output.However, MR Configurator is necessary for positioning operation.
