ECODRIVE Drive Controller DKC02.1
F245 External Encoder Failure: Quadrant Error
A hardware fault has been detected in the external measuring system’s
high-resolution position interface for sinusoidal signals.
Cause:
1.
2.
3.
Defective encoder cable
Interference on encoder cable
Defective amplifier
Remedial action:
Ref. 1. Replace the encoder cable
Ref. 2. Lay the encoder cable separately from power cables
Ref. 3. Replace the amplifier
F248 Low Battery Voltage
Cause:
In a motor of the MKD series, the absolute position information is stored
in a battery-backed electronics system in the motor feedback. The
battery has been designed for a utilization period of 10 years. This
message is output if the battery voltage drops below 2.8 V. The function
of the absolute encoder is ensured for another two weeks.
CAUTION
Hazard:
Faults in controlling motors and/or moved
elements may lead to injuries.
⇒ Action:
Replace battery as soon as possible
Preparation for changing batteries
The following parts are required:
• Size 10 TORX screwdriver
• Flat nose pliers; torque wrench
• New pre-assembled battery (order no.: 257101)
CAUTION
Hazard:
Faults in controlling motors and/or moved
elements may lead to injuries.
⇒
Switch off the power supply and secure it
against being switched on again. Replace
the battery while the control voltage is
switched on.
If the control voltage were switched off while the battery is disconnected,
the right reference point would be lost and must be re-established.
