d35
Overspeed Detection Level
d35 specifies the overspeed detection level under torque control by percentage of the maximum frequency (F03, A01,
b01, r01).
If the following condition is satisfied, the inverter detects an overspeed state and issues an overspeed alarm
Motor speed ≥ Maximum frequency (F03/A01/b01/r01) × d35
Setting d35 data to "999" causes the inverter to issue an overspeed alarm
conditions is satisfied.
Motor speed ≥ Maximum frequency (F03/A01/b01/r01) × (d32 or d33) × 1.2
or
Motor speed ≥ 200 Hz (vector control with speed sensor) or 120 Hz (vector control without speed sensor)
× (d32 or d33) × 1.2
Torque/Torque current command
It is possible to command torque/torque current from an analog voltage input (terminal [12] or [V2]) or analog
current input (terminal [C1]), or via the communications link (function codes S02 and S03).
(To use the analog voltage/current input, function codes E61 (terminal [12]), E62 (terminal [C1]), and E63
(terminal [V2]) should be set to 10 or 11 as shown in the table below.
Input
Terminal [12]
(-10 V to 10 V)
Terminal [V2]
(-10 V to 10 V)
Terminal [C1]
(0, 4 to 20 mA)
S02
(-327.68 to 327.67%)
S03
(-327.68 to 327.67%)
Function codes C31 to C45 (Analog input adjustment) are applied to these analog inputs.
