Description
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the speed calculation gain during usual operation. Usually it is not necessary to
change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the speed calculation gain during a speed search.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the speed range to operate with the pull-in current command. Drive rated frequency
= 100% value. If there is a large quantity of oscillation when you operate in the low
speed range, increase the setting value.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the function to adjust for changes in the motor resistance value caused by changes
in the temperature.
0 : Invalid
1 : Valid (Only 1 time)
2 : Valid (Every time)
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the gain for magnetic flux compensation. Usually it is not necessary to change this
setting.
Description
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets, as a percentage, the Initial Rotor Position Estimated Current, taking the E5-03
[Motor Rated Current (FLA)] as the 100% value. Usually it is not necessary to change
this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the current at the time of polar attraction as a percentage where E5-03 [motor rated
current] is 100%. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets how the drive detects the position of the rotor when the motor starts.
Note:
• When you use an SPM motor, set n8-35 = 0. When you use an IPM motor, set n8-
35 = 0 to 2.
• When you set n8-35 = 1, do High Frequency Injection Auto-Tuning.
0 : Pull-in
1 : High Frequency Injection
2 : Pulse Injection
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the injection frequency for high frequency injection.
Note:
• Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-
57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter.
• The drive automatically calculates this value when High Frequency Injection
Auto-Tuning completes successfully.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the high frequency injection amplitude as a percentage where 200 V = 100% for
200 V class drives and 400 V = 100% for a 400 V class drives. Usually it is not
necessary to change this setting.
Note:
• Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-
57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter.
• The drive automatically calculates this value when High Frequency Injection
Auto-Tuning completes successfully.
