Limits
Speed limits and current limits drive setting:
T current lim
Current limit setting (see chapter 6.5.2 for more details).
Flux current max
Maximum field current value as percentage of Motor fld curr.
Flux current min
Minimum field current value as percentage of Motor fld curr. (See chapter 6.5.3 for
more details).
Speed min amount
Minimum speed reference limit. (see chapter 6.5.1 for more details).
Speed max amount
Maximum speed reference limit. (see chapter 6.5.1 for more details).
Speed feedback
Speed feedback setting (see chapter 6.11.4 for more details) :
Speed fbk sel
Speed feedback selection
Tacho scale
Tach generator feedback scaling (Speed fbk sel must be set to Tacho)
Speed offset
Speed feedback offset
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
Overvoltage and Overcurrent threshold setting (see chapter 6.11.7 for more details) :
Undervolt thr
AC input alarm threshold value
Overcurrent thr
Overcurrrent alarm threshold value.
Overload control
Current overload setting (see chapter 6.14.6 for more details) :
Enable overload
Current overload control enabling.
Overload mode
Overload current mode selection (Curr limited, Curr not limited, I2t Motor, I2t Drive,
I2t motor & I2t drive)
Overload current
Drive output current permissible during the overload time
Base current
Drive output current permissible during the pause time
Overload time
Maximum time in which the Overload current is permissible.
Pause time
Minimum time between overload cycles.
