(1) Servo amplifier errors (2000 to 2799)
The servo amplifier errors are errors detected by the servo amplifier and are
assigned error codes 2000 to 2799.
In the following tables, the types of servo amplifier are indicated for MR-[ ]-B.
The servo error detection signal (M1608+20n) comes ON when a servo error
occurs. Eliminate the cause of the error, reset the error by turning ON the servo
error reset signal (M1808+20n), and reset operation. (Note that the servo error
detection signal will not come ON in response to error codes in the range 2100
to 2499 because these codes are for warnings.)
Note: 1. When an excessive regeneration error (code 2030), or overload 1 or 2
error (codes 2050, 2051) occurs, the state that applied when the error
occurred is stored in the servo amplifier even after the protection circuit
has operated. The memory contents are cleared if the external power
supply is turned OFF, but are not cleared by the reset signal.
2. Repeated resetting by turning OFF the external power supply after
occurrence of error code 2030, 2050, or 2051, may cause devices to
be destroyed by overheating. Only restart operation after eliminating
the cause of the error.
Details of servo errors are given in Table 2.14.
