5.5 E: Motor Parameters
204 YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual
■ E4-11: Motor 2 Rated Power
Sets the motor 2 rated power. If Auto-Tuning completes successfully, the value entered to T1-02 will automatically be
saved to E4-11.
◆ E5: PM Motor Settings
These parameters set the motor data of a PM motor.
When Yaskawa motors are used, entering the motor code written on the motor nameplate will set up the E5-
parameters.
For all other PM motors, Auto-Tuning can be performed. If motor data is known, it can also be entered manually.
Note: 1. E5- parameters are visible only when a PM motor control mode is selected (A1-02 = 5, 6, or 7).
2. E5- parameters are not reset when the drive is initialized using parameter A1-03.
■ E5-01: Motor Code Selection
When Yaskawa motors are used, set the motor code for the PM motor being used. Depending on the motor code entered,
the drive automatically sets several parameters to appropriate values. Refer to Parameters that Change with the Motor
Code Selection on page 463 for details on the supported motor codes and their parameter settings.
Setting parameter E5-01 to FFFF will allow to set the motor data manually using the E5- parameters.
Note: 1. If E5-01 was set a value besides FFFF and is then changed to FFFF, the value of parameters E5-02 through E5-24 will not change.
2. If using a different motor other than Yaskawa’s SMRA, SSR1, or SST4 series, then E5-01 should be set to FFFF.
3. The default setting is below:
• OLV/PM, AOLV/PM: Yaskawa SSR1 Series (1750 r/min)
• CLV/PM: Yaskawa SSR4 Series (1750 r/min)
■ E5-02: Motor Rated Power
Sets the rated power of the motor. Determined by the value set to T2-04 during Stationary Auto-Tuning for PM motors or
by entering the motor code to E5-01.
■
E5-03: Motor Rated Current
Sets the motor rated current in amps. This parameter is automatically set when the value is entered to T2-06 during the
Auto-Tuning process.
Note: This value's number of decimal places depends on the drive model and the Heavy/Normal duty selection in parameter C6-01.
The value will have two decimal places (0.01 A) if the drive is set for a Maximum Applicable Motor Capacity up to 11 kW (refer
to Table A.2 and Table A.3) and one decimal place (0.1 A) if the set Maximum Applicable Motor Capacity is higher than 11 kW.
■ E5-04: Number of Motor Poles
Sets the number of motor poles. This parameter is automatically set when the value is entered to T2-08 during the Auto-
Tuning process.
