Highest speed
The highest speed of the Speed1 is selected with the SPD H/L switch (function
setting switch No.1).
Select either 200 r/min or 600 r/min for the highest speed.
The speed, which can be set with the speed setting switch, differs in
200 r/min and 600 r/min. Check a desired speed with the tables on p.14 to
p.15.
OFF: 600 r/min
ON: 200 r/min
Factory setting: OFF (600 r/min)
z
Setting method for the Speed2
The setting method for the Speed2 is selected with the SPD2 EN (function
setting switch No.2).
OFF: Fixed to a 10% speed of the Speed1
ON: Selected one from 16 different speeds in a range of 0.5 to 50% of the
Speed1
Factory setting: OFF (Fixed to a 10% speed of the Speed1)
z
Operating speed
The operating speed varies depending on the setting pattern.

y
Speed1 ...........Check a desired speed from 256 different speeds in the tables
on p.14, and set using a combination of the ×16/SPD1 switch
and the ×1/SPD2 switch.
y
Speed2 ...........This is fixed to a 10% speed of the Speed1.
•
Pattern 2
y
Speed1 ...........Check a desired speed from 16 different speeds in the tables
on p.15, and set with the ×16/SPD1 switch.
y
Speed2 ...........Check a desired speed from 16 different speeds in the tables
on p.15, and set with the ×1/SPD2 switch.
z
Acceleration time and deceleration time
The acceleration time refers to the time needed for the operating speed to
reach 600 r/min from 0 r/min. The deceleration time refers to the time needed
for the operating speed to reach 0 r/min from 600 r/min. The same time is
applied to all of the acceleration, deceleration, and changing speed.
Set using the ACC0 to ACC2 switches (function setting switch No.4 to No.6).

Operating current rate and standstill current rate
•
Operating current rate
If the load is small and there is an ample allowance for torque, the motor
temperature rise can be suppressed by setting a lower operating current rate.
The actual operating current is a value that the rated operating current of the
driver is multiplied by the operating current rate.
Operating current = Driver rated current × Operating current rate
Select the operating current rate using the RUN switch (function setting
switch No.3).
OFF: Operating current rate 100%
ON: Operating current rate 70%
Factory setting: OFF (100%)
Set the operating current rate to 70% when using the
CVD524BR-
KSC
with an accessory circuit product cover.
•
Standstill current rate
When the motor stops, the current cutback function will be actuated to lower
the motor current to the standstill current. The standstill current rate is 50% of
the operating current.
Standstill current = Operating current × 50%
Alarm
When the driver's protective function triggers and an alarm generates, the
ALM output is turned OFF and the motor current is cut off. At the same time,
the PWR/ALM LED will blink in red. The cause of the alarm can be checked by
counting the number of times the PWR/ALM LED blinks.

Cause and remedial action
2
Overheat
[Cause]
The temperature of the driver circuit board
reached 85 °C (185 °F).
[Remedial action]
Review the ventilation condition.
3
Overvoltage
[Cause]
A voltage exceeding the specification value was
applied.
[Remedial action]
Check the input voltage of the power supply.
[Cause]
A large inertial load was stopped abruptly or
vertical operation was performed.
[Remedial action]
If this alarm generates during operation, reduce
the load or increase the acceleration/deceleration
time.
5
Overcurrent
[Cause]
An excessive current was flowed through the
driver output circuit for motor.
[Remedial action]
Turn off the power and check that the motor,
cable and driver are not damaged.
[Cause]
The motor was made a quick stop or a rapid
deceleration.
[Remedial action]
Review the operating conditions.
9
EEPROM error
[Cause]
The stored data in the driver was damaged.
[Remedial action]

Lit
CPU error
[Cause]
CPU malfunctioned.
[Remedial action]
Cycle the power.
