5.1 INPUT POWER SUPPLY
5.1.1 Three-phase Input Power Supply for Motor Power
- Nominal rated voltage: 200 to 240 VAC
- Allowable voltage fluctuation: -15% to +10%
- Frequency: 50/60 Hz
- Allowable frequency fluctuation: ±2 Hz
- Power supply impedance: Voltage fluctuation cased by load (at
maximum output) not to exceed 7%
- Power supply unbalance: Within ±5% of the rated voltage
NOTE
The allowable voltage fluctuation is a change
observed for several minutes. It is not a continuous
change.
5.1.2 Single-phase Input Power Supply for Motor Power
In European countries, power sources are 380 to 415 VAC and
neutral-grounded. To use the β series amplifiers in these European
countries, it is necessary to install a power transformer at the input or
supply single-phase power.
To use the motors with single-phase power, observe the following:
(1) Power supply specification
- Nominal voltage rating: 220 to 240 VAC
- Allowable voltage fluctuation: -15% to +10%
- Frequency: 50/60 Hz
- Allowable frequency fluctuation: ±2 Hz
- Voltage fluctuation at acceleration/deceleration: 7% or less
NOTE
The allowable voltage fluctuation is a change
observed for several minutes. It is not a continuous
change.
5.1.3 Single-phase Input for Control Power
- Nominal rated voltage: 24VDC
- Allowable voltage fluctuation: ±10% (including momentary
variations)
- Power supply ratings
