M1.15-1 Generator speed threshold ”GenSpdTh”
This set the speed range in which the Controller is gradually increasing the regenerating power capability.
Regenerative power is gradually opened (starting from 0%) above the speed set by means of Analogue input 2,
up to 100% when speed is greater or equal to the speed set by means of Analogue input 2 plus the value of this
parameter.
Too low values could bring to unstable generator behaviour.
How does “Generator mode” works
Generator mode is activated when “M2-4 Digital input 7 configuration ”Spd3/Hbk”” is set to 3 and the switch connected
to Digital Input 7 is closed.
In this situation the Digital Inputs 1, 2, 3 and 4 (FW, RV, FS, ST) and the Analog Input 1 (Accel pot) will not be active.
Analog Input 2 (Brake pot) will be used to set the regenerative braking speed set point.
When generator mode is active no drive torque will be allowed, meaning that the motor will not be accelerated to the
generating speed set point set by means of Analog Input 2.
Brake torque (regeneration power) will be allowed gradually when speed rises above the generating speed set point set
by means of Analogue input 2. Full braking torque is available if speed is above the speed set point plus an adjustable
threshold in % set by means of “M1.15-1 Generator speed threshold ”GenSpdTh””.
Brake torque limit is managed by the generating function as following graph:
Analog Input 3 (Steer pot) will be used to set the maximum generator power, by cutting the regenerative current limit.
In case the user is sending a regenerative BCL to the controller, the value of the Analogue input 3 will be used to rescale
the said value.
If any brake torque limitation becomes active in the controller, the regenerative power will be automatically cut to the
said level.
