FOLLOWER / CONTROL OUTPUT P2/2
CO Mode
Control Output Mode (CP-270) affects the range of Control Output (CO_Sig) analog signal sent out to the
drive.
3 = Unipolar Reversible
2 = Bipolar (default)
1 = Unipolar
CO Max Volts
Control Output Maximum Volts (CP-271) sets the upper limit on the voltage sent to the drive. Bipolar operation
assumes plus or minus this value. It should be set equal, or lower, than the input specifications of the drive.
CO Plrty
Control Output Polarity (CP-272) determines whether a positive, or negative, signal voltage will operate the drive in the
forward direction, under the most basic normal operation.
2 = Negated (neg=fwd)
1 = Normal (pos=fwd) (default)
CO Offset
Control Output Offset (CP-273) adjusts for small variations in the specifications of certain IC devices on this particular
controller board. Usually a very small number, it serves to true up the 0 volts end point of the output voltage scale. It
is preset at the factory, and should not need field adjustments.
CO Volts
Control Output Volts (MP-37) displays the present value, in volts, of the Control Output (CO_Sig) signal to the drive.
It is the combination of FeedFwd (MP-35) plus Trim Out (MP-36).
CO Bits
Control Output Bits (MP-38) displays the present value, in DAC bits, of the Control Output (CO_Sig) signal to the
drive. CO Bits is the CO Volts (MP-37) expressed in DAC bits.
CO Max Bits
Control Output Maximum Bits (MP-39) reflects the maximum allowed output in units of DAC bits. The value of CO Max
Volts (CP-271) determines this parameter, based on the conversion of 32767 bits = 15 VDC.
