JOG
The JOG function only works when the drive is in REMOTE mode, and only when
the drive is in a STOP condition. TB-13B can be programmed to select either JOG
FORWARD or JOG REVERSE. The jog speed is set by PRESET SPEED #2. Close
TB-13B to TB-2 to JOG, and open the contact to STOP.
WARNING!
W hen operating in JOG mode, the STOP key WILL NOT stop the drive.
To stop the drive, the contact between TB-13B and TB-2 must be opened.
MOP - MOTOR OPERATED POT
TB-13A and TB-13B are used for this function, which sets the speed of the drive
using contacts wired to the terminal strip. Program TB-13A to select DEC FREQ,
and program TB-13B to select INC FREQ. Closing TB-13A to TB-2 will activate the
DEC FREQ function, and will cause the speed set point to decrease until the contact
is opened. DEC FREQ will operate when the drive is in RUN mode or STOP mode.
Closing TB-13B to TB-2 will activate the INC FREQ function, and will cause the
speed set point to increase until the contact is opened. INC FREQ will only operate
when the drive is in RUN mode.
NOTE: If TB-13A, TB-13B, and TB-13C are all programmed to select speed
references, and two or three of the terminals are closed to TB-2, the higher terminal
has priority and will override the others. For example, if TB-13A is programmed
to select 0-10VDC, and TB-13C is programmed to select PRESET SPEED #3,
closing both terminals to TB-2 will cause the drive to respond to PRESET SPEED
#3, because TB-13C overrides TB-13A.
14.2.7 ANALOG OUTPUT SIGNALS
There are two terminals that can supply analog output signals proportional to
output frequency or load. Terminal TB-10A can provide a 0-10 VDC or a 2-10 VDC
signal proportional to output frequency, and TB-10B can provide the same signals
proportional to load. The 2-10 VDC signals can be converted to a 4-20 mA signal
using a resistor in series with the signal such that the total load resistance is 500
Ohms. Refer to Parameters: 42 - TB10A OUT, 43 - @TB10A, 44 - TB10B OUT, and
45 - @TB10B in Section 18 - DESCRIPTION OF PARAMETERS.
NOTE: These analog output signals cannot be used with “loop-powered” devices
that derive power from a 4-20 mA signal.
14.2.8 DRIVE STATUS OUTPUT CONTACTS
The control board has one Form C relay at terminals TB-16, TB-17, and TB-18.
Contacts are rated 2 amps at 28 VDC or 120 Vac.
NOTE: Models rated above 30 Hp at 200/240 Vac and 60 Hp at 400/480 Vac have
a second Form C relay at terminals TB-19, TB-20, and TB-21.
There are also two open-collector outputs at terminals TB-14 and TB-15. The open-
collector circuit is a current-sinking type rated at 30 VDC and 40 mA maximum. An
external power supply (30 VDC max) must be used to power the open-collector outputs.
The drive does not have a dedicated power supply for the open-collector outputs.
The Form C relay and the open collector outputs can be programmed to indicate
any of the following: RUN, FAULT, /FAULT (INVERSE FAULT ), LOCK (FAULT
LOCKOUT ), AT SPEED, ABOVE #3, I LIMIT (CURRENT LIMIT ), or AUTO/MAN.
See Parameters: 52 - TB14 OUT, 53 - TB15 OUT, and 54 - RELAY. Refer to Section
6.2.5 for a complete description of each of these status indications.
