Chapter 4. WIRING
• If the motor connected to the motor drive relay output is used with a 100/200VAC
power supply, the use of an external auxiliary relay is recommended. If an auxiliary
relay is not used, thoroughly check the operating conditions (operating voltage of
the motor, inrush current, frequency of switching, etc.) before use.
• Do not wire in the same duct for the motor drive terminals 13, 14, 15 and the
MFB input terminals 7, 8, 9 and also do not use 6-core cable.
Doing so might cause the unit to malfunction due to noise at start-up of the
motor.
• Make sure that devices and equipment connected to this device have reinforced
insulation suitable for the maximum operating voltage of this device's power
supply and input/output ports.
• This unit has been designed to start functioning after an initial stabilization
period of 5 seconds after power ON, in order to ensure stable operation. After
that, the unit then enters the operation mode. However, to satisfy the specified
accuracy, it is necessary to warm up the unit for at least 30 min.
IMPORTANT
Terminating resistor
• Do not connect any terminating resistor in the RS-485 communication path.
Doing so might cause the communication failure.
