When the inverter outputs the frequency set in the Creep Speed Setting (P015) or higher, if the
speed feedback value does not reach the Starting Frequency (b082) within the Encoder Disconnec-
tion Detection Time (P077), the inverter detects the E80.
(Encoder disconnection error) and shuts
off the output.
If the inverter falsely detects this error, for example, when it operates with a heavy load and is slow
to start, some adjustment is required. Use the Creep Speed Setting (P015) and Encoder Disconnec-
tion Detection Time (P077) to set speed and time values that allow the inverter to start stably in your
application.
When the Pulse Train Input RP Selection (P003) is set to 01 (Feedback pulse), the monitor functions
listed below are always enabled.
Use these monitor functions for checking the operation of the simple position control function, monitor-
ing device position, or other purposes.
Because the Digital Operator of this inverter has a 4-digit display, you can monitor only the upper 4 dig-
its.
To monitor a value over 4 digits, use the computer tool CX-Drive.
