4.1 How to use drive recorder

When an alarm occurs at the servo amplifier, the conditions (such as motor speed and droop pulses) of the
servo amplifier before/after alarm occurrences will be recorded. You can refer to the recorded data with MR
Configurator2.
The drive recorder records sixteen data at alarm occurrences in the past. Occurring an alarm deletes the
oldest data. However, sixteen data at alarm occurrences are recorded in total of A-axis, B-axis, and C-axis
for MR-J4W_-_B. Therefore, alarms fewer than sixteen will be displayed on the alarm history display for
each axis.
POINT
When you use the J3 extension function, replace the following left parameters to
the right parameters.
[Pr. PF21] → [Pr. PX30]
[Pr. PA23] → [Pr. PX29]
The drive recorder will not operate on the following conditions.
You are using the graph function of MR Configurator2.
You are using the machine analyzer function.
[Pr. PF21] is set to "1".
The controller is not connected (except the test operation mode).
You are operating in the J3 compatibility mode.
When the following alarms occur, the drive recorder will not operate.
[AL. 10.1 Voltage drop in the control circuit power]
[AL. 12 Memory error 1 (RAM)]
[AL. 15 Memory error 2 (EEP-ROM)]
[AL. 16 Encoder initial communication error 1]
[AL. 17 Board error]
[AL. 19 Memory error 3 (Flash-ROM)]
[AL. 1A Servo motor combination error]
[AL. 1E Encoder initial communication error 2]
[AL. 1F Encoder initial communication error 3]
[AL. 25 Absolute position erased]
[AL. 37 Parameter error]
[AL. 70 Load-side encoder initial communication error 1]
[AL. 888/88888 Watchdog]
[AL. 8D.1 CC-Link IE communication error 1] (For MR-J4-_GF_(-RJ), the drive
recorder operates by setting [Pr. PN06] to "_ _ _ 1".)
[AL. 8D.2 CC-Link IE communication error 2] (For MR-J4-_GF_(-RJ), the drive
recorder operates by setting [Pr. PN06] to "_ _ _ 1".)
When the graph is displayed with MR Configurator2, the drive recorder function
will be enabled. After the graph function is completed, passing time set with [Pr.
PF21] or cycling the power of the servo amplifier will enable the drive recorder
function again. For MR-J4-_A_(-RJ), enabling/disabling the drive recorder
function can be made with the display (diagnostic mode).
