5.5.4: Linear Motor Setup Parameters
View or change the settings described below. Options vary with amplifier model. Metric units are shown
here.
S
etting Description
Manufacturer Motor maker’s name. Saved in the motor data file. Choose from list or enter
manually.
Model Number Motor model number. Saved in the motor data file. Choose from list or enter
manually.
Units Selects whether the parameters entered in this screen are in Metric or English
units.
Mass The mass of the motor. Used for calculating initial velocity loop tuning values.
Range: .0001 Kg to 100,000 Kg. Default: .0001 Kg.
Peak Force The peak force that the motor can produce. Peak Force divided by Force Constant
= motor’s peak current limit. Range: 0.00001 to 2,000 N. Default: 0.00001 N.
Continuous Force The continuous force that the motor can produce. Used with the force constant to
calculate continuous current. Range: 0.00001 to 1,000 N. Default: 0.00001 N.
Velocity Limit Maximum speed of the motor. Used to calculate the velocity and acceleration
limits for the velocity loop. Range dependent on encoder resolution.
Force Constant Relates the motor's input current to force produced. Sometimes abbreviated as Kf.
Range: 0.00001 to 2,000 N/Amp. Default: 0.00001 N/Amp.
Back emf Constant Relates the motor's input voltage to speed. Sometimes abbreviated as Ke. Used
for calculating maximum velocity for a given amplifier voltage.
Range: 0.01 to
1,000 V/M/Sec. Default: 0.01 V/M/Sec.
Resistance Motor resistance line to line. Used for calculating the initial current loop tuning
values. Range: 0.01 to 327 . Default: 0.01 .
Inductance Motor inductance line to line. Used for calculating the initial current loop tuning
values. Range: see Power Output (p. 36).
Magnetic Pole Pair Length The length of a pair of magnets which equals the distance moved in one electrical
cycle of the motor.
