function
Improves a disturbance response when a response performance cannot be
increased because of a large load to motor inertia ratio, such as a roll feed axis.
Suppresses vibration of ±1 pulse generated at a servo motor stop.
The position control is performed based on a value obtained by multiplying the
position command from the controller by the set electronic gear ratio.
Enables smooth acceleration and deceleration.
Set S-pattern acceleration/deceleration time constants with [Pr. PC03].
As compared with linear acceleration/deceleration, the acceleration/deceleration
time will be longer for the S-pattern acceleration/deceleration time constants
regardless of command speed.
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 servo
amplifier does not have sufficient regenerative capacity for a large regenerative
power generated.
Clears alarm histories.
ST1 (Forward rotation start), ST2 (Reverse rotation start), and SON (Servo-on) and
other input device can be assigned to certain pins of the CN3 connector.
The output devices including MBR (Electromagnetic brake interlock) can be
assigned to certain pins of the CN3 connector.
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.
Servo motor speed can be limited to any value.
Voltage is automatically offset to stop the servo motor if it does not come to a stop
when VC (Analog speed command) is 0 V.
MR Configurator2 is necessary for this function.
If an alarm has occurred, the corresponding alarm number is outputted in 3-bit code.
Jog operation, positioning operation, motor-less operation, DO forced output,
program operation, and single-step feed
MR Configurator2 is necessary for this function.
Using a personal computer, you can perform the parameter setting, test operation,
monitoring, and others.
Gain adjustment is performed just by one click on MR Configurator2.
This function is available with MR Configurator2 or via a network.
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
by clicking the Waveform-Display button in the drive recorder window of MR
Configurator2.
However, the drive recorder is not available when:
1. You are using the graph function of MR Configurator2.
2. You are using the machine analyzer function.
3. [Pr. PF21] is set to "-1".
You can check the cumulative energization time and the number of on/off times of the
inrush relay. This function gives an indication of the replacement time for parts of the
servo amplifier including a capacitor and a relay before they malfunction.
This function is available with MR Configurator2 or via a network. (Refer to section
6.4.)
