Description of Parameters
610 Torque limit control P-gain 6 (P1.10.2)
This parameter defines the gain of the torque limit controller.
611 Torque limit control I-gain 6 (P1.10.3)
This parameter determines the I-gain of the torque limit controller.
612 CL: Magnetizing current 234567 (P1.6.12.1, P1.6.15.1)
Sets the motor magnetizing current (no-load current). See Page A-3.
613 CL: Speed control P-gain 234567 (P1.6.12.2, P1.6.15.2)
Sets the gain for the speed controller in % per Hz. See Page A-3.
614 CL: Speed control I-time 234567 (P1.6.12.3, P1.6.15.3)
Sets the integral time constant for the speed controller. Increasing the I-time increases
stability but lengthens the speed response time. See Page A-3.
615 CL: Zero speed time at start 234567 (P1.6.12.9, P1.6.15.9)
After giving the start command the drive will remain at zero speed for the time
defined by this parameter. The ramp will be released to follow the set frequency/
speed reference after this time has elapsed from the instant where the command is
given. See Page A-3.
616 CL: Zero speed time at stop 234567 (P1.6.12.10, P1.6.15.10)
The drive will remain at zero speed with controllers active for the time defined by this
parameter after reaching the zero speed when a stop command is given. This
parameter has no effect if the selected stop function (ID506) is Coasting. See Page A-3.
617 CL: Current control P-gain 234567 (P1.6.12.17, P1.6.15.17)
Sets the gain for the current controller. This controller is active only in closed loop and
advanced open loop modes. The controller generates the voltage vector reference to
the modulator. See Page A-3.
618 CL: Encoder filter time 234567 (P1.6.12.18, P1.6.15.18)
Sets the filter time constant for speed measurement.
The parameter can be used to eliminate encoder signal noise. Too high a filter time
reduces speed control stability. See Page A-3.
619 CL: Slip adjust 234567 P1.6.12.6, P1.6.15.6)
The motor name plate speed is used to calculate the nominal slip. This value is used
to adjust the voltage of motor when loaded. The name plate speed is sometimes a
little inaccurate and this parameter can therefore be used to trim the slip. Reducing
the slip adjust value increases the motor voltage when the motor is loaded. See
Page A-3.
