Indication Status error Action
01 SFR (normal rotation command), SRV (reverse
rotation command), or ORCM (orientation
command) is entered when *ESP (emergency stop
signal, which may be a input signal or contact
signal) and MRDY (machine ready signal) are not
applied.
Check the sequence of *ESP and MRDY. For
MRDY, check bit 0 of parameter No. 4001,
specifying whether to use the MRDY signal.
02 When the spindle and spindle motor are specified
separately (with bit 5 of parameter No. 4001 set to
1, and bit 6 of parameter No. 4001 set to 0) in a
system employing a high–resolution magnetic pulse
coder, 128 /rev must be set for the motor speed
detector (bits 2, 1, and 0 of parameter No. 4011
must be set to 0, 0, and 1, respectively). However, a
value other than 128 /rev is set. In such a case, the
motor is not activated.
Check the parameter settings.
03 The Cs contouring control command is input
although bit 5 of parameter No. 4001 is set to 0 to
specify that a high–resolution magnetic pulse coder
is not used or although bit 4 of parameter No. 4018
is set to 0 to specify that the a sensor Cs contouring
control function is not used. In such a case, The
motor is not activated.
Check the parameter settings.
04 When bit 2 of parameter No. 4001 is set to 0 to
specify that a position coder signal is not used, a
command for servo mode control (rigid tapping, Cs
axis control, etc.) or spindle synchronization control
is entered. In such a case, the motor is not
activated.
Check the parameter setting enabling the use of a
position coder signal.
05 When the option parameter of the orientation
function is not set, ORCM (orientation command) is
entered.
Check the parameter setting enabling the use of the
orientation function.
06 When the option parameter of the speed range
switching control function is not set, winding for
low–speed characteristics is selected (with RCH =
1).
Check the setting of the parameter for using the
speed range switching control function, and the
power line status check signal (RCH).
07 When the Cs contouring control command is
entered, neither SFR (normal rotation command)
nor SRV (reverse rotation command) is entered.
Check the sequence.
08 When a servo mode control command (rigid
tapping, Cs axis control, etc.) is entered, neither
SFR (normal rotation command) nor SRV (reverse
rotation command) is entered.
Check the sequence.
09 When the spindle synchronization control command
is entered, neither SFR (normal rotation command)
nor SRV (reverse rotation command) is entered.
Check the sequence.
10 When the Cs contouring control command is
entered, a another mode (such as the servo mode,
spindle synchronous control, and orientation) is
specified.
When Cs contouring control is specified, do not
specify another mode. To enter another mode, first
cancel the Cs contouring control command.
11 When a servo mode control command (rigid
tapping, Cs axis control, etc.) is entered, another
mode (such as Cs contouring control, spindle
synchronization control, and orientation) is
specified.
When a servo mode is specified, do not specify
another mode. To enter another mode, first cancel
the servo mode command.
12 When the spindle synchronization control command
is entered, another mode (Cs contouring control,
servo mode, or orientation) is specified.
When spindle synchronization control is specified,
do not specify another mode. To enter another
mode, first cancel the spindle synchronization
control command.
