3.8 Power
Sets the power of the wheelchair.
Adjustable in steps of 1% from 0 to 100%.
Power is the ability of a wheelchair to climb a hill or overcome an obstacle. If it is set to 100% then the wheelchair will provide full
power. Values below 100% will result in reduced power.
A typical use is to minimise damage to doorways or furniture if the wheelchair is being used indoors. The values can be set
independently between drive profiles, meaning separate indoor and outdoor profiles can be defined.
Example: newVSI is programmed to:
Current Limit Max. = 50 Amps
Power (Profile 1) = 50%
Power (Profile 2) = 25%
3.9 Number of Drive Profiles
Refer to section 1.4.
3.10 Minimum Acceleration
Adjusts the minimum value for forward and reverse acceleration of the wheelchair.
Adjustable in increments of 1% of the Acceleration value.
This percentage of the Acceleration value occurs when the newVSI speed setting is at it’s minimum 1 bar illumination.
See following example.
Acceleration = 80 and Minimum Acceleration = 25%
Acceleration at step 1 = 25% of 80 = 20
Speed settings 2, 3 and 4 will interpolate linearly between 20 and 80
Acceleration at step 2 = 35
Acceleration at step 3 = 50
Acceleration at step 4 = 65
3.11 Minimum Deceleration
Adjusts the minimum value for forward and reverse deceleration of the wheelchair.
Adjustable in increments of 1% of the Deceleration value.
This percentage of the Deceleration value occurs when the newVSI speed setting is at it’s minimum 1 bar illumination.
See following example.
Deceleration = 80 and Minimum Deceleration = 25%
Deceleration at step 1 = 25% of 80 = 20
Speed settings 2, 3 and 4 will interpolate linearly between 20 and 80
Deceleration at step 2 = 35
Deceleration at step 3 = 50
Deceleration at step 4 = 65
