SRDY is activated when the servo drive is
7 6 ready to run. All fault and alarm conditions, if
present, have been cleared.
SON is activated when control power is
applied the servo drive. The drive may or may
not be ready to run as a fault / alarm
condition may exist.
- -
Servo ON (SON) is "ON" with control power
applied to the servo drive, there may be a
fault condition or not. The servo is not ready
to run. Servo ready (SRDY) is "ON" where the
servo is ready to run, NO fault / alarm exists.
ZSPD is activated when the drive senses the
motor is equal to or below the Zero Speed
Range setting as defined in parameter P1-38.
For Example, at factory default ZSPD will be
5 4
activated when the drive detects the motor
rotating at speed at or below 10 r/min, ZSPD
will remain activated until the motor speed
increases above 10 r/min.
TSPD is activated once the drive has detected
the motor has reached the Target Rotation
- - Speed setting as defined in parameter P1-39.
TSPD will remain activated until the motor
speed drops below the Target Rotation Speed.
1. When the drive is in PT mode, TPOS will
be activated when the position error is
equal and below the setting value of P1-
54.
2. When the drive is in PR mode, TPOS will
be activated when the drive detects that
1 26 the position of the motor is in a -P1-54 to
+P1-54 band of the current command
position. For Example, at factory default
TPOS will activate once the motor is in -99
pulses range of the current command
position, then deactivate after it reaches
+99 pulses range of the desired position.
TQL is activated when the drive has detected
that the motor has reached the torques limits
- -
set by either the parameters P1-12 ~ P1-14 of
via an external analog voltage.
ALRM is activated when the drive has detected
a fault condition. (However, when Reverse
limit error, Forward limit error, Emergency
28 27
stop, Serial communication error, and
Undervoltage these fault occur, WARN is
activated first.)
