In this mode, the motor will produce full rated torque up to 60 Hz. Above 60 Hz,
torque will linearly reduce to 50% at 120 Hz.
Figure 6 - Graph showing reduction in motor torque at frequencies above 60 Hz.
AC LINE VOLTAGE SELECTOR JUMPERS – There are three voltage selector
jumpers that must be repositioned if the input line voltage is 230 VAC instead of
115 VAC. If the control is to be operated from a 230 VAC power supply, pull out
the voltage selector jumpers J1, J2, and J10 from their “115V” positions and
reinsert them into their “230V” positions. See Figure 4 for the locations of the
jumpers.
CAUTION
Connecting 230 VAC to a control configured for 115 VAC will
permanently damage the control.
AC LINE FUSE JUMPER WIRE – If the control is to be operated from a two-
phase 230 VAC power supply, where both lines are hot (typically in the USA),
then remove the jumper wire between the spades labeled “J5” and “J8.”
AC LINE FUSES – Model 2995 has a 12A fuse already installed in both the “F1”
and “F2” fuse holders. A fuse is only really necessary in “F2” if a two-phase 230
VAC power supply (with two hot sides) is used.
