V/f operation for hoist applications: Improved features (VVC + Imin control) (from V01.07.04)
Function extension:
Motor control mode V/f characteristic control of asynchronous motors (ASM) in hoist applications:
The characteristics when holding the load at standstill and at low speeds have now been improved.
In addition to the set static current (parameter 0x2B04 V/f boost control - setpoint current), a further additive current can now be set in 0x2B05:003.
This current is impressed in addition to the setpoint current when the motor is accelerated.
This allows the stall current to be set lower, resulting in less motor heating, while still building up high torque during acceleration due to the additional current.
Contained in which products?
Servo-Inverter i950 FW: from V01.07.04.2313
Application:
Hoist applications with asynchronous motor (ASM) without feedback system.
