4. PARAMETERS
Specify the alarm No. in parameter No. PC44 when operating the drive recorder with the specific alarm No.
Specification of alarm No.
00 : No specification
(The optimum item is recorded according to the alarms that have occurred
earlier and operating conditions.)
01 to FFh : Specification
(The specified item is recorded when an alarm of the specified alarm No. occurs.)
When a non-existent alarm No. is specified, the specified value is recognized as "00h".
Parameter No. PC44
0
(2) Record data
(a) When the set value of parameter No. PC44 is "
00":
1) When alarms to be recorded by the drive recorder function are in the alarm history:
The specified data are automatically selected and recorded based on the alarm history.
a) Analog CH data
Three data for 3CH are automatically selected from the data listed below.
Servo motor speed [r/min] Torque [%]
Bus voltage (Note) Within one-revolution position [pulse]
Multi-revolution counter [rev] Current command [%]
Regenerative load ratio [%] Command pulse frequency [kpps]
Effective load ratio [%]
Note. The bus voltage is displayed in five steps.
