Parameter Values
Start/Stop Velocity
(1) (2)
(1) The parameter is set as REAL (float) value in Connected Components Workbench. To learn more about conversions and rounding of
REAL values, see Real Data Resolution on page 108 .
(2) The formula for deriving rpm to user unit, and vice versa:
The range is based on Motor and Load parameters (See Motor and Load Parameters
on page 104 ) using:
Range 1…100,000 pulse/sec
Default : 300 rpm
For example, you can configure the value from 0.005…500 mm/s for 200 pulses per
revolution and units of 1 mm per revolution.
(3)
Rpm value is automatically populated when a value in user units is specified, but the
user can also initially enter an rpm value.
Start/stop velocity should not be greater than maximum velocity.
(3) To convert from parameter value from pulse to user units:
Start/Stop Velocity in rpm
(1) (2)
Max Velocity
(1) (2)
The range is based on Motor and Load parameters (See Motor and Load Parameters
on page 104 ) using:
Range: 1…10,000,000 pulse/sec.
Default: 100,000.0 pulse/sec
Max Acceleration
(1)
The range is based on Motor and Load parameters (See Motor and Load Parameters

Max Deceleration
(1)
The range is based on Motor and Load parameters (See Motor and Load Parameters
on page 104 ) using:
Range : 1…100,000 pulse/sec

Stop Jerk
(1)
The range is based on Motor and Load parameters (See Motor and Load Parameters
on page 104 ) using:
Range : 0...10,000,000 pulse/sec

A red border on an input field indicates that an invalid value has been
entered. Scroll over the field to see tooltip message that will let you know
the valid value range for the parameter. Supply the valid value.
v (in rpm) =
v (in user unit/sec) x 60 s
travel per revolution (in user unit)
Value in user unit = Value in pulse x
Travel per revolution
Pulse per revolution
