Limits
This menu allows setting of speed limits value, current limits value and field current limits when different from
the default values in Motor data menu.
T current limit Armature current limit value as percentage of Full load curr. When overload function is used this
value must be equal or higher than Overload current parameter value (Overload function).
Flux current max Maximum field current value as percentage of Motor nom flux.
Flux current min Minimum field current value as percentage of Motor nom flux. It corresponds to the
Speed-0 f weak current value when Speed-0 f weak function is active and it will be the
lower field current limit value when the motor is running in Voltage control range.
Speed min amount Minimum speed reference limit.
Speed max amount Maximum speed reference limit.
Speed feedback setting
Speed fbk sel Speed feedback selection: encoder 1, encoder 2, tach generator, armature (CEMF).
Tacho scale Tach generator feedback scaling (Speed fbk sel must be set to Tacho)
Encoder 2 pulses Number of pulses per revolution of the digital encoder to the XE2 connector.
Enable fbk contr Speed feedback loss control. The Motor max speed, Max out voltage, Flux weak
speed parameters must be set correctly according to the motor used.
Refresh enc 2 Enable the monitoring of the encoder 2 (XE2 connector) connection status (A , B, Anot,
Bnot channels). Enable fbk contr must be enabled.
Alarms
Undervolt thr AC input alarm threshold value.
Overcurrent thr Overcurrrent alarm threshold value.
Overload control
The overload control function allows an overcurrent for a limited time that can exceed the rated current of the drive.
It is used in order to provide an increased acceleration torque.(See Overload control function for more details).
Analog inputs 1, 2 and 3
Three (3) differential analog inputs programmable are available (1-2, 3-4, 5-6 terminals) that allow a large
number of configurations.
With the standard setting, analog input 1 (1 - 2 terminals) is set to Ramp ref 1. The other analog inputs are set to OFF.
