1. FUNCTIONS AND CONFIGURATION
1 - 12
Machine analyzer function
Analyzes the frequency characteristic of the mechanical system by simply connecting an
Setup software (MR Configurator2
TM
) installed personal computer and the driver.
Setup software (MR Configurator2
TM
) is necessary for this function.
For roll feed axis, etc. of which a response level cannot be increased because of the large
load to motor inertia ratio, this function improves a disturbance response.
Slight vibration suppression
control
This function suppresses vibration of ±1 pulse generated at a servo motor stop.
Positioning control is performed with the value obtained by multiplying the position
command from the upper side by a set electronic gear ratio.
S-pattern
acceleration/deceleration time
constant
Speed can be increased and decreased smoothly.
Automatically adjusts the gain to optimum value if load applied to the servo motor shaft
varies.
Use a regenerative option when the built-in regenerative resistor of the driver does not
have sufficient regenerative capacity for a large regenerative power generated.
Input signal selection (device
settings)
The input devices including LSP (forward rotation stroke end) and LSN (reverse rotation
stroke end) can be assigned to certain pins of the CN3 connector.
Output signal selection (device
settings)
The output devices including MBR (Electromagnetic brake interlock) can be assigned to
certain pins of the CN3 connector.
Output signal (DO) forced
output
Turns on/off the output signals forcibly independently of the servo status.
Use this function for checking output signal wiring, etc.
Limits the servo motor torque.
The servo motor speed can be limited.
Shows servo status on the 3-digit, 7-segment LED display.
JOG operation, positioning operation, motor-less operation, DO forced output, program
operation and single-step feed
Setup software (MR Configurator2
TM
) is necessary for this function.
Outputs servo status with voltage in real time.
Setup software (MR
Configurator2
TM
)
Using a personal computer, you can perform the parameter setting, test operation,
monitoring, and others.
Gain adjustment is performed just by one click a certain button on Setup software (MR
Configurator2
TM
).
Also, one-touch tuning can be performed via a network. For details, refer to respective
communication method manuals of "MR-J4-_TM_ Driver Instruction Manual".
This function enables to avoid triggering [AL. 10 Undervoltage] using the electrical energy
charged in the capacitor in case that an instantaneous power failure occurs during
operation. Use a 3-phase for the input power supply of the driver. Using a 1-phase 100 V
AC/200 V AC for the input power supply will not comply with SEMI-F47 standard.

[Pr. PF25]
Section 7.4
This function makes the equipment continue operating even under the condition that an
alarm occurs.
The tough drive function includes two types: the vibration tough drive and the
instantaneous power failure tough drive.
This function continuously monitors the servo status and records the status transition
before and after an alarm for a fixed period of time. You can check the recorded data on
the drive recorder window of Setup software (MR Configurator2
TM
) by clicking the "Graph"
button.
However, the drive recorder is not available when:
1. You are using the graph function of Setup software (MR Configurator2
TM
).
2. You are using the machine analyzer function.
3. [Pr. PF21] is set to "-1".
4. The upper side is not connected (except the test operation mode).
5. An alarm related to the upper side has occurred.
