Servo alarm

Output signal indicating that the alarm is on.
Output transistor turns on in normal condition, and output transistor turns off
when alarm is on.

• This output signal can be used by choosing positioning completion output
(COIN) or output during deceleration (DCLON) by SV.Pr64.
COIN: When the amount of position deviation pulse is within the range set by
SV.Pr60 (In-position range), the transistor turns on. However, while the
operation command is being processed, it will not turn ON even inside the
positioning completion range.
DCLON: Transistor turns ON while the motor is decelerating. However, the
signal is not output when the motor has stopped because the deceleration
time is zero.
Motor operation
condition output
BUSY 28
• Transistor turns OFF while the servo driver is processing operation
command.
<Notes>
When an operation command has been started by the strobe signal input
(STB), the motor operation status output remains OFF until the strobe
signal input is set to the opened condition.
Present posi-
tion output
• Outputs the present motor position (point number) when the step operation
is completed.
• All the transistors are OFF (point 0) when the power is turned on. However,
when the absolute mode is established or when the 16.Pr38 is set to 1
(homing is invalid), the maximum point number set in the SV.Pr57
(Selecting the number of input points) is output.
• Upon completion of homing, the maximum point number set in the SV.Pr57
(Selecting the number of input points) is output.
• During high-speed normal rotation jog operations, the maximum point
number set in the SV.Pr57 (Selecting the number of input points) minus 1 is
output after the motor has stopped.
• During high-speed reverse rotation jog operations, the maximum point
number set in the SV.Pr57 (Selecting the number of input points) minus 2 is
output after the motor has stopped.
When an alarm has occurred, all the transistors are set OFF.
<Note>
When an operation has been aborted because of servo OFF,
instantaneous stop or deceleration stop, the last status is held as the
current position output. To obtain the correct output, move to the reference
position (home point, absolute position command point).

Brake release
output
BRK-OFF 36
• Defines the timing signal to activate the electromagnetic brake for the motor.
When the electromagnetic brake is released, the output transistor turns ON.
• Output timing of this signal can be set by SV.Pr6A (Mechanical brake delay
at motor standstill) and SV.Pr6B (Mechanical brake delay at motor in
motion).

• Division-processed encoder signal or external scale signal (A/B-phase) is
output in differential mode. (RS422)
• SV.Pr44 (numerator of output pulse ratio) and SV.Pr45 (denominator of
output pulse ratio) can be used to set the division ratio.
• SV.Pr46 (pulse output logic inversion) can be used to select the logic
relation of phase B with regard to the pulse of phase A, and its output
source.
• Ground of line driver of the output circuit is connected to signal ground
(GND); not insulated.
• The maximum output frequency is 4 Mpps (after being multiplied by 4).
• Open collector output of Z-phase signal.
• Emitter side of the transistor of the output circuit is connected to signal
ground (GND); not insulated.
