Current Limit Values
The current limit values used for selection calculation are listed below.
Item Current limit values for selection calculation
Control power (CP) 9.0A or less
Motor power (MP) 37.5A or less
Check that the results from the calculations of the control power supply and the motor power
supply based on the construction of REC System would not exceed the current limit.
Note that the EC gateway unit is not included in the calculations.
Calculation examples are shown below.
[Control power] * The EC gateway unit is not included in the calculations.
For ELECYLINDER × 16 axes ……… EC Connection Unit 0.1A × 4
＝
0.4A ⇒ OK
[Motor Power Supply]
When ELECYLINDER (with power saving mode invalid)
×
16 axes
…………… EC Connection Unit rated current 2.3 A
×
16 axes = 91.2 A
⇒
OK
Note For those with no description of the rated current for the motor current amperage,
calculate with the maximum current.
Note Supposing that the operation pattern is that all axes only perform
acceleration/deceleration simultaneously, and operating duty is 100%, the motor power
must be calculated by using the maximum current value.
When it is necessary to calculate the motor power supply in detail,
use the “calculator software” to figure out the current amperage for
ELECYLINDER. Set up the operating conditions and the operation
patterns of an actuator, and it automatically calculates the
necessary current amperage.
Refer to "Calculator Instruction Manual (ME0381)" for details such
as how to operate.
