5. Alarm Occurs
*1) The motor will stop per Deceleration Stop Method (No.224.0) as follows.
2 (quick stop) or 1 (short brake) : the motor decelerates and stops by short brake.
0 (Free-run) : no brake.
*2) Deceleration Stop Status ends when deceleration stop conditions set by the parameters (No.224.1, No.226.0, and No.227.0) are met.
*3) Timing of MBRK turning OFF
If Deceleration Stop Method (No.224.0) = 2 (quick stop) or 1 (short brake),
MBRK turns OFF when one of the following conditions is met.
1) Deceleration Stop Status turns OFF
2) Motor Rotational Speed drops to the value specified by the parameter No.227.0 or below.
If Deceleration Stop Method (No.224.0) = 0 (no brake),
MBRK turns OFF when Motor Excitation Status turns OFF.
If any of the following alarms occurs,
MBRK turns OFF when the internal error status becomes ERROR .
a) Encoder related errors b) Control Power voltage drop error
c) Errors related to Inverter output part d) Overvoltage error
If any alarm except above four occurs, the motion pattern will be exactly as this timing diagram suggests.
*4) Deceleration Stop behaves as follows depending on the error type:
a) Encoder related errors: Deceleration Stop per Deceleration stop operating time (Parameter No.226.0)
b) Control Power voltage drop error: Deceleration Stop per Deceleration stop (upon control power failure) Operating time (No.228.0)
c) Errors related to Inverter output part: Free-run
*5) In case of the following alarms, Servo Status will remain ON until Deceleration Stop Status turns OFF.
a) Encoder related errors
b) Control power voltage drop error
