Parameters
8.2.4 High performance motor control
Par. Description Range Default Explanation
P4-01 Control mode 0: Speed control (vector)
1: Torque control (vector)
2: Speed control (V/f) 2 Whenever changing control mode, ensure that an
Auto-tune (P4-02) is always carried out for best motor
performance. Set to 0 for speed control with variable
torque limits.
P4-02 Motor parameter auto-tune 0: Disable
1: Enable
0 When set to 1, drive immediately carries out a static
(non-rotating) motor parameter measurement opera-
tion to configure the motor parameters. P1-07, P1-08
and P1-09 must be set correctly according to the
motor nameplate before enabling this function.
Auto-tune runs automatically on first enable after
parameter default operation and P1-08 have been
changed. No hardware enable is required.
P4-03 Speed controller
Proportional gain 0 … 4096 (internal value) Drive
rating Too high a value can cause instability. Only available
in vector mode.
P4-04 Speed controller Integral
time constant 0.000 … 1.000 s 0.05 s Higher value gives slower, more damped response.
Only available in vector mode.
P4-05 Motor factor power 0.50 … 0.99 Drive
rating Motor nameplate power factor (cos
Φ
).
Required for all vector control modes.
P4-06 Torque reference select 0: Preset value
1: Bipolar analog input
2: 2nd analog input
3: MODBUS ref 0 Used when in vector control mode to set a maximum
torque limit.
P4-07 Torque reference preset
value 0 … 200 % 200.0 % Preset value used when P4-06 = 0. 100 % is rated
motor torque.
P4-08 Minimum torque reference
limit 0 …150 % 0.0 % Defines the minimum limit for output motor torque
P4-09 V/f characteristic adjust-
ment frequency 0 … P1-09 0.0 Hz Sets the frequency at which the adjustment voltage
(P4-10) is applied.
P4-10 V/f characteristic adjust-
ment voltage 0 … P1-07 0 Sets the motor voltage to this value at the frequency
set in P4-09.
