12.6 E: Motor Parameters
754 YASKAWA SIEPC71061705H GA700 Series Technical Manual
◆ E5: PM Motor Settings
E5 parameters are used to set PM motor data.
Set E5-01 to the motor code when using PM motors recommended by Yaskawa. E5 and other related motor
parameters will be automatically set to the optimal values.
Perform Auto-Tuning for all other PM motors. If information from motor nameplates or test reports is available,
the E5 parameters can be manually entered.
Note:
• The keypad displays E5-xx only when A1-02 = 5, 6, 7 [Control Method Selection = OLV/PM, AOLV/PM, CLV/PM].
• E5-xx parameters are not reset when the drive is initialized using parameter A1-03 [Initialize Parameters].

• 0.1 A: models 2056 - 2415, 4031 - 4675
The drive automatically sets E5-03 to the value input for “PM Motor Rated Current” after you do these types of
Auto-Tuning:
• Manual Entry w/ Motor Data Sheet
• PM Stationary Auto-Tuning
• Stationary (R Only)
• Rotational (Ld, Lq, R, back-EMF)

Determined by E5-01
(2 - 120)
Note:
• When A1-02 = 7 [Control Method Selection = CLV/PM], the maximum value is 120.
• When A1-02 = 5, 6 or 8 [OLV/PM, AOLV/PM or EZOLV], the maximum value is 48.
