Option
Description
Scaling
Current mode: output current produced by +10 Vdc of input.
Range: 0 to 10,000,000 A. Default: Peak Current value.
Velocity mode: output velocity produced by +10 Vdc of input.
Range: 0 to 100,000 rpm (mm/sec).
Default: Maximum Velocity value.
Position mode: position change (counts or mm) produced by +10 Vdc of input.
Range: 0 to 1,000,000,000 counts.
Default: 1 Revolution of a rotary motor or 1 pole pair distance for a linear motor.
For more information, see Scaling (p. 25).
Dead Band
Sets dead band. Range: -10,000 to 10,000 mV. Default: 0.
For more information, see Dead Band (p. 25).
Invert
Command
Inverts polarity of amplifier output with respect to input signal.
Offset
(Current and Velocity modes only.) Used to offset input voltage error in an open loop
system. Not recommended for use when the amplifier is part of a closed loop system.
Range: -10,000 to 10,000 mV. Default: 0. For more information, see
Offset (p. 26).
Analog Input
Filter
Programmable input filter. Disabled by default. See “Low-Pass and Bi-Quad Filters” in
the CME 2 User’s Guide.
