<8> Parameter value is changed if E2-11 is manually changed or changed by Auto-Tuning.
<9> Default setting is determined by the drive model (o2-04) and duty selection (C6-01).
<10> Default setting is determined by the control mode (A1-02).
<14> Default setting value is dependent on the motor code set to parameter E5-01.
<18> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
<33> Default setting value is dependent on the setting for the input voltage (E1-01).
<34> Setting range is dependent on the control mode (A1-02). When using CLV, OLV/PM, or AOLV/PM, the setting range is 0 to 2 s.
<35> The upper limit of the setting range is determined by the values set to the duty selection (C6-01) and the carrier frequency reduction selection
(L8-38).

All Modes
Sets the proportional gain used to calculate the deceleration rate during KEB Ride-Thru, ov
suppression function, and Stall Prevention during deceleration (L3-04 = 2).
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the deceleration time used for Stall Prevention during acceleration in OLV/PM.
V/f V/f w/PG
OLV/PM AOLV/PM
0: Sets the Stall Prevention level set in L3-06 that is used throughout the entire frequency range.
1: Automatic Stall Prevention level reduction in the constant output range. The lower limit
value is 40% of L3-06.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time needed to accelerate the uncoupled motor at rated torque from stop to the
maximum frequency.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the ratio between the motor and machine inertia.
All Modes
When DC bus capacitors have been added externally, be sure to add those values to the internal
capacitor table for proper DC bus calculations.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time the current must exceed the Stall Prevention level to activate Stall Prevention.
All Modes
L4-01 sets the frequency detection level for digital output functions H2-
L4-02 sets the hysteresis or allowable margin for speed detection.
All Modes
L4-03 sets the frequency detection level for digital output functions H2-
L4-04 sets the hysteresis or allowable margin for speed detection.
All Modes
0: Stop. Drive stops when the frequency reference is lost.
1: Run. Drive runs at a reduced speed when the frequency reference is lost.
All Modes
Sets the percentage of the frequency reference that the drive should run with when the
frequency reference is lost.
All Modes
0: No detection during baseblock.
1: Detection always enabled.
