Lenze SX-1 - P3-P6 Speed and Acceleration Parameters; P3-P6 Parameters

P3: Analog Voltage to Speed Ratio (Vo/Vm) [ratio
]
The value entered is the ratio of the speed used to the nominal speed multiplied by the
reference voltage tor nominal speed.
P3 = •Vin
Units: Ratio
Range: 0.1 to 9.9
Nrated = maximum motor speed
Nused = maximum speed used
Vin = reference for maximum speed
P4: Scanning rate (T)
The scanning rate should not be changed by the user: it is only used tor tests.
The smallerthe time, the betterthe control quality. Standard values are 3 ms for 1 ncremen -
tal Encoder, and 5 ms tor Absolute Encoder. With control over the loop from external
Override or Interpolation, P4 must always be set to 5 ms.
P5: Maximum speed (max. V) [Unitsls]
Units for PS: Length Units (mm, inch, degrees, etc) per second.
Range:0.1 ... 6000.0
Vk • nmax =Vmax 1
Vk = Feed constant (Units/Revolution at gearbox output)
n max = maximum speed of motor and controller combination
= Reducer ratio
P6: Maximum Acceleration (max A) [Units/s
2]
Units tor P6: Distance Units (mm, inch, degrees, etc) per second2
Range: 0.1 ... 60,000
The maximum acceleration may be calculated as follows:
