• Securely connect the power supply terminal screws and motor output terminal screws.
Failure to observe this caution may result in fire.
• Do not bundle or run power and signal lines together in the same duct. Keep power and signal
lines separated by at least 30 cm (11.81 in).
• Use twisted-pair shielded wires or multi-core twisted pair shielded wires for signal and encoder
(PG) feedback lines.
The maximum length is 3 m (118.11 in) for reference input lines and is 20 m (787.40 in) for PG feedback
lines.
• Do not touch the power terminals for 5 minutes after turning power OFF because high voltage may
still remain in the SERVOPACK.
Make sure the charge indicator is out first before starting an inspection.
• Avoid frequently turning power ON and OFF. Do not turn power ON or OFF more than once per
minute.
Since the SERVOPACK has a capacitor in the power supply, a high charging current flows for 0.2 seconds
when power is turned ON. Frequently turning power ON and OFF causes main power devices like capacitors
and fuses to deteriorate, resulting in unexpected problems.
• Be sure to wire correctly and securely.
Failure to observe this caution may result in motor overrun, injury, or malfunction.
• Always use the specified power supply voltage.
An incorrect voltage may result in burning.

the conventional SERVOPACK models that had been introduced before Σ-series, using the latest technologies in
its circuit configuration.
The re-engineered AC SERVOPACK supports all the types of encoders for AC servodrives: serial encoders and
encoders older than serial encoders
The re-engineered AC SERVOPACK provides the operating environment of the following conventional
SERVOPACK models.
• Recognizes the encoder type prior to Σ series by the switch setting
(An encoder signal converter is built in.)
• Important adjustments such as speed gain adjustment can be made
using the potentiometers VR.
(In the same way as of the conventional models CACR-SRBB and BZ)
1.2.2 Updated with the Latest Technologies
• The basic functions and performance are equivalent to those of Σ-III
series SERVOPACK
• The parameters of Σ-III series SERVOPACK are applied.
(Parameter setting using a digital operator.)
1.2.3 Wide Range of Applicable Servomotors
The re-engineered AC SERVOPACKs can be combined with various models of servomotors by setting the internal parameters: C series, M series, F series, G series, D series, S series, Σ-series, Σ-II series, and Σ-III series Servomotors.

Limit at Servo ON
Different multi-turn limits have been
set in the encoder and SERVOPACK.
Position error pulse exceeded parameter (Pn520).
When the servo turns ON, the position error pulses exceeded the parameter setting (Pn526).
If the servo turns ON with position
error pulses accumulated, the speed is
limited by Pn529. In this state, the
reference pulse was input without
resetting the speed limit, and the position error pulses exceeds the value set
for the parameter Pn520.

OverloadThis warning occurs before the overload alarms (A.710 or
A.720) occur. If the warning is ignored and operation continues, an overload alarm may occur.
VibrationAbnormal vibration at the motor speed was detected. The
detection level is the same as A.520. Set whether to output
an alarm or warning by “Vibration Detection Switch” of
Pn310.
Regenerative OverloadThis warning occurs before the regenerative overload
alarm (A.320) occurs. If the warning is ignored and operation continues, a regenerative overload alarm may occur.
