6 Vector Control and Applied Functions
6 - 38 Multi-function Compact Inverter 3G3MX2-V1 User’s Manual (I585-E1)
Simple position control has protective functions. Set these functions according to your application.
If the Reset Selection (C102) is set to 02 (Enabled only during trip, default), 00 (Trip reset at power-on),
or 01 (Trip reset at power-off), the current position data is cleared when a trip is reset.
Set the Reset Selection (C102) to 03 (Trip reset only) so as not to clear the current position data.
z
Position control range trip
If the Current Position Monitor (d030) value is out of the position control range specified in the Posi-
tion Limit Setting (P072 and P073), the inverter detects the E83.
(Position control range trip) and
shuts off the output. Set the parameter value according to the moving range for your application.
Because the Digital Operator of this inverter has a 4-digit display, you can set only the upper 4 digits.
To set a value over 4 digits, use the computer tool CX-Drive.
z Overspeed error detection
If the speed feedback value exceeds the value set in the Overspeed Error Detection Level (P026),
the inverter detects the E81.
(Overspeed error) and shuts off the output.
Set the detection level according to the maximum speed allowable for your application.
z Speed deviation excessive level detection
If the deviation of the actual frequency from the frequency reference value exceeds the value set in
the Speed Deviation Excessive Level (P027), the inverter outputs the excessive speed deviation sig-
nal (DSE). Although the inverter outputs this signal, it does not shut off its output (trip).
In this case, set the Multi-function Output P1/P2 Selection (C021/C022), or the Multi-function Relay
Output (MA, MB) Function Selection (C026), to 22 (DSE: Excessive speed deviation). In addition,
construct such a sequence that stops the control if the inverter outputs the excessive speed devia-
tion signal (DSE).
