Parameter Details

u 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.

n 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 Parameter Defaults Determined by Motor

Code (E5-01) on page 431 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)

4. Some selections may not be available depending on the motor code that has been selected.

n 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.

n 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.

E5-05: Motor Stator Resistance (r1)

Set the resistance for one motor phase. When measuring the resistance manually, make sure not to enter the line-to-line

resistance into E5-05.
