MHT258a (Engl.)9-12
(g) High voltage, overvoltge
• Touch panel display
• Detection (example)
The DC intermediate voltage in the amplifier is higher than the upper limit.
• Cause, check and remedy
(h) Amp heat, amplifier overheat
• Touch panel display
• Detection (example)
The temperature of cooling-fins of the amplifier is above 100 [°C]
• Cause, check and remedy
The ambient temperature for the amplifier should be below +55 [°C]
(i) Encoder communication error
• Touch panel display
• Detection (example)
The communication is not made between 16-bit serial encoder and amplifier.
• Cause, check and remedy
The encoder wiring may be detached or disconnected.
The serial communication is performed at 4[Mbps] of data rate. Do not extend the wiring by connecting several short cables.
Connect the encoder by option cable or specified cables.
The encoder wiring has about 5[V] of voltage amplitude. Do no install it in a location where a strong electric or magnetic field exists.

Power capacitor is turned ON/OFF
on same line.
Occurs when turning on power. Power supply voltage may be higher than specified.
Study a use of AC reactor.
Braking resistor is connected. Study a use of external braking resistor (0.2 [kW] max.).
Braking resistor is free from
disconnect.
Check the resistance of braking resistor.
For resistance of braking resistor, see 10.6.
