6 Connection
Be certain the control input/output cable that connects the driver and
Note
•
controller is as short as possible. The maximum input frequency will
decrease as the cable length increases.
When a large inertial load is operated at high speed, regenerative
•
energy will generate and increase the power supply voltage, which can
damage the driver. When performing the operation described above,
change the operating conditions so that any temporary rise in supply
voltage due to regenerative energy will not exceed 6 V.
Connecting the I/O and power supply
Connecting the I/O power supply wires into the driver's I/O and power supply
terminal blocks (TB1). Screw terminals are used. Remove the insulation from the
core, then insert the core into the terminal and tighten with terminal screws.
Strip 5 mm (0.2 in.) of insulation. Tighten the terminal screw to the specified
tightening torque.
• Use a cable of AWG 22 to 18 for the power supply line.
Tightening torque: 0.22 to 0.25 N·m (1.95 to 2.2 lb-in)
• Use a cable of AWG 24 to 20 for the I/O line.
Tightening torque: 0.22 to 0.25 N·m (1.95 to 2.2 lb-in)
Be sure to check the setting of the power supply voltage switch. Refer to page 35.
• Power supply voltage
Use a power supply that can supply the following current capacity.
Driver model
Power supply
input voltage
Power supply
current capacity
Pay attention to polarity when connecting the power supply. Connecting
Note
•
the power supply in reverse polarity may damage the driver.
Do not wire the driver's power supply cable in the same conduit in which
•
another power line or the motor cable is wired.
After turning off the power supply, wait at least 5 seconds before turning
•
it on again.
