2. Wire Emergency Coast Stop Circuit (ECOAST).
The drive has the capability to accept an ECOAST input from either a
24VDC or 115VAC contact. The contact must be normally closed and
will typically be a Stop pushbutton. Refer to the following paragraphs,
Figure 4.5 and Table 4.J for connection information.
If a 24VDC ECOAST is desired, the contacts of the ECOAST device
must be wired between terminals 9 and 11 of TB3. Jumpers must then
be connected between terminals 4 and 5 and 10 and 12 of TB3.
If a 115VAC ECOAST is desired, the contacts of the ECOAST device
must be wired between terminals 4 and 5 of TB3. Jumpers must then
be connected between terminals 9 and 11 and 10 and 12 of TB3.

ATTENTION: Applying improper input voltage could damage
the Power Stage Interface Board. Jumpers J11 and J12 on the
Power Stage Interface Board must be set for the proper input
voltage before applying power to these inputs.
3. Wire the Motor Thermostat Circuit. Terminal TB3-2 is used to receive
either a 24VDC or 115VAC input (derived from an external voltage
source) when the motor thermostat contact is closed. The contacts of
the motor thermostat must be N.C. The drive interprets a high voltage
at TB3-2 as a normal expected condition. Refer to Figure 4.5 for
further connection information.
4. Reset/Normal Stop.
This input is programmable to provide either a System Reset function
or a Normal Stop function. It accepts a 115VAC or 24VDC input
voltage. System Reset Select (parameter 620) determines which
function this input provides.
The System Reset function requires a N.O. operator device which
closes to cause a reset. A reset input causes the drive to perform a
power-up sequence. Any data not previously stored in EEPROM
memory will be lost.
The Normal Stop function requires a N.C. operator device. When
opened, the
drive will stop (the type of stop is determined by Param
624). This may be used to provide an additional stop to the drive.
