User Manual Chapter 7 - Parameters Description 65
S.202 Ref 1 Channel (Reference 1 channel)
It defines the source from where the Reference 1 is provided and controlled.
For further details please refer to chapter FREQ & RAMPS, section Reference Source.
S.203 Frequency ref 0 (Frequency reference 0)
Digital speed reference.
It is also the first digital frequency of the Multispeed selection (F.100F.116).
It is possible to set setting with positive or negative values.
The polarity will determine the sense of rotation of the motor.
In either polarity the setting the HW Reverse command is active (when enabled).
The maximum settable value is correlated to Max ref freq (S.201).

(****) parameter value dependent on drive type.
S.300 Acc time 1 (Acceleration time 1)
S.301 Dec time 1 (Deceleration time 1)
The ramp control can be set to allow a programmable delay (in seconds), for the acceleration and deceleration
times of the drive reference.
This delay time will have to be set on the final system (motor and load), being strictly dependant from the inertia
of the load machine.
The ramps time delay, are calculated in accordance with the Max ref freq (S.201).
The setting can be carried out as follows, according to the setting of the parameter F.200.

Functions
S.400 Manual boost [%]
The resistive impedance of the stator windings causes a voltage drop within the motor, which result in a reduction
in torque in the lower speed range.
Compensation can be made for this effect by boosting the output voltage.
This compensation is carried out continuously across the whole speed range in proportion to the output current
but it is most effective at low speed.
