Description

Torque Comp

This parameter helps to produce better starting torque. It
determines the amount of torque or voltage boost based upon
motor current and motor resistance.
This parameter adjusts a filter on the output of the torque
compensation function. Increase to add torque stability, decrease
to improve torque response.

Carrier Freq

Reduced Current Rating
Standard Current Rating
Carrier frequency sets the number of pulses per second of the out-
put voltage waveform.
0: Low Noise (Carrier frequency is randomly moduled for lower
audible noise)
1: Fc = 2.0 kHz
2: Fc = 5.0 kHz
3: Fc = 8.0 kHz
4: Fc = 10.0 kHz
5: Fc = 12.5 kHz
6: Fc = 15.0 kHz
F: Program (Determined by the settings of C6-03 thru C6-05)
Maximum carrier frequency allowed when C6-02 = F.
Minimum carrier frequency allowed when C6-02 = F.
Sets the relationship of output frequency to carrier frequency when
C6-02 = F.

Preset Reference (Speeds)

Digital preset speed command 1. Used when b1-01 = 0. Setting
units are affected by o1-03.
Digital preset speed command 2. Selected via multi-function input
terminals. Setting units are affected by o1-03.
Digital preset speed command 3. Selected via multi-function input
terminals. Setting units are affected by o1-03.
Digital preset speed command 4. Selected via multi-function input
terminals. Setting units are affected by o1-03.
Speed command used when a jog is selected via multi-function
input terminals. Setting units are affected by o1-03.
