n n9: Hardware Settings
n8-54
(56DH)
Voltage Error Compensation Time
Constant
Adjusts the value when hunting occurs at low speed. If hunting occurs with sudden load
changes, increase n8-54 in increments of 0.1. Reduce this setting if oscillation occurs at start.
Default: 1.00 s
Min: 0.00 s
Max: 10.00 s
241
n8-55
(56EH)
Load Inertia
Sets the ratio between motor and machine inertia.
0: less than 1:10.
1: between 1:10 to 1:30.
2: between 1:30 to 1:50.
3: higher than 1:50.
Default: 0
Min: 0
Max: 3
241
n8-57
(574H)
High Frequency Injection
0: Disabled. Disable when using an SPM motor.
1: Enabled. Use this setting to enhance the speed control range when using an IPM motor.
Default: 0
Min: 0
Max: 1
242
n8-62
(57DH)
Output Voltage Limit
Prevents output voltage saturation. Should be set just below the voltage provided by the input
power supply.
Default: 200.0 V
<15>
Min: 0.0 V
Max: 230.0 V
<15>
242
n8-65
(65CH)
Speed Feedback Detection Control
Gain during ov Suppression
Sets the gain used for internal speed feedback detection during ov suppression
Default: 1.50
Min: 0.00
Max: 10.00
242
n8-69
(65DH)
Speed Calculation Gain
Sets the proportional gain for PLL control of an extended observer.
There is normally no need to change this parameter from the default value.
Default: 1.00
Min: 0.00
Max: 20.00
242
n8-84
(2D3H)
Polarity Judge Current
Sets the current to determine polarity for the initial polarity calculation as a percentage of the
motor rated current.
Default: 100%
Min: 0%
Max: 150%
243
<7> Default setting value is dependent on the motor code set to E5-01.
<15> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
No. (Addr.)
<9> Default setting value varies by the drive model (o2-04).

n9-10
(5D9H)
AVR Time Constant
Sets a delay time for output voltage compensation.
Default: 1.0 ms
Min: 0.0 ms
Max: 100.0 ms
243
n9-12
(5DBH)
On-Delay Compensation Time
Sets the time value used for IGBT On-delay compensation.
Default:
<9>
Min: 0.00 μs
Max: 20.00 μs
243
n9-62
(64FH)
On-Delay Compensation Derating
Start Frequency
Sets the frequency at which the drive begins to compensate the output voltage for the IGBT On-
Delay.
Default: 60.0 Hz
Min: 0.0 Hz
Max: E1-04
243
n9-63
(650H)
On-Delay Compensation Disable
Frequency
Sets the frequency at which the drive stops compensating the output voltage for the IGBT On-
Delay.
Default: 120.0 Hz
Min: 0.0 Hz
Max: E1-04
