7.4.3. Advanced Parameters
Vector speed control mode for Induction Motors
V/f mode for Induction Motors
PM vector speed control for Permanent Magnet Motors
BLDC vector speed control for Brushless DC Motors
SR vector speed control for Synchronous Reluctance Motors
LSPM vector speed control for Line Start Permanent Magnet Motors
This parameter can be used to optimise the performance when P-51 = 0. Autotune is not required if P-51 = 1. For settings 2 – 5 of P-
51, autotune MUST be carried out AFTER all other required motor settings are entered.
When enabled, the drive immediately measures required data from the motor for optimal operation. Ensure
all motor related parameters are correctly set first before enabling this parameter.
Single Parameter for Vector speed loop tuning. Affects P & I terms simultaneously. Not active when P-51 = 1.
Defines the max current limit in vector control modes
Motor stator resistance in Ohms. Determined by Autotune, adjustment is not normally required.
Motor Stator d-axis Inductance (Lsd)
Determined by Autotune, adjustment is not normally required.
Motor Stator q-axis Inductance (Lsq)
Determined by Autotune, adjustment is not normally required.
Sets the speed at which DC injection current is applied during braking to Stop, allowing DC to be injected before the drive reaches
zero speed if desired.
Sets the level of DC injection braking current applied according to the conditions set in P-32 and P-58.
Index 1: Thermal Overload Retention
When enabled, the drive calculated motor overload protection information is retained after the mains power
is removed from the drive.
Index 2: Thermal Overload Reaction
When the motor thermal overload accumulator reaches 100%, the drive will trip and display
it.trp
When the motor thermal overload accumulator reaches 90%, enabled, output current will be
limited to 100% of the value of P-08, which will result in output frequency reduction. This can
be used in applications such as fans and pumps where it is desired to have triples operation,
and the current limiting / frequency reduction can protect against transient high loads
without affecting the normal operation of the application.
