E2: Motor 1 Parameters - YASKAWA A1000 HHP Programming Manual

Note: 1. The following condition must be true when setting up the V/f pattern: E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04
2. To make the V/f pattern a straight line below E1-06, set E1-09 equal to E1-07. In this case the E1-08 setting is disregarded.
3. E1-03 is unaffected when the drive is initialized, but E1-04 through E1-13 return to their default values.
4. Only use E1-11, E1-12, and E1-13 to fine-tune the V/f pattern in the constant output range. These parameters rarely need to be changed.

E2: Motor 1 Parameters

These parameters contain the motor data needed for motor 1. Performing Auto-Tuning (including Rotational Auto-Tuning
and Stationary Auto-Tuning 1 and 2) automatically sets these parameters.
217 for details if Auto-Tuning cannot be performed.
Note: The function for switching between two motors cannot be used with a PM motor. E2-oo parameters are hidden when a PM motor control
mode is selected (A1-02 = 5, 6, or 7).
n E2-01: Motor Rated Current
Provides motor control, protects the motor, and calculates torque limits. Set E2-01 to the full load amps (FLA) stamped on
the motor nameplate. If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to E2-01.
No.
E2-01
Note: 1. The number of decimal places in the parameter value depends on the drive model and the ND/HD selection in parameter C6-01. This
value has two decimal places (0.01 A) if the drive is set for a maximum applicable motor capacity up to and including 11 kW, and one
decimal place (0.1 A) if the maximum applicable motor capacity is higher than 11 kW.
2. An oPE02 error will occur if the motor rated current in E2-01 is set lower than the motor no-load current in E2-03. Set E2-03 correctly
to prevent this error.
n
E2-02: Motor Rated Slip
Sets the motor rated slip in Hz to provide motor control, protect the motor, and calculate torque limits. This value is
automatically set during Auto-Tuning (Rotational Auto-Tuning, Stationary Auto-Tuning 1 and 2).
No.
E2-02
If Auto-Tuning cannot be performed, calculate the motor rated slip using the information written on the motor nameplate and
the formula below:
E2-02 = f - (n × p)/120
(f: rated frequency (Hz), n: rated motor speed (r/min), p: number of motor poles)
n
E2-03: Motor No-Load Current
Set the no-load current for the motor in amperes when operating at the rated frequency and the no-load voltage. The drive sets
E2-03 during the Auto-Tuning process (Rotational Auto-Tuning and Stationary Auto-Tuning 1, 2). The motor no-load current
listed in the motor test report can also be entered to E2-03 manually. Contact the motor manufacturer to receive a copy of the
motor test report.
