L1, L2, L3 Line input supply terminals for models H3-2035 to H3-2330:
(R, S, T) Connect to either 3ø, 50Hz, 200VAC or 3ø, 60Hz, 200 to 230VAC.
Line input supply terminals for models H3-4055 to H3-420K:
Connect to either 3ø, 50HZ, 400VAC or 3ø, 60Hz, 400 to 460VAC.
Drives can be operated on single phase power with when
appropriately derated; contact Toshiba distributor for information.
T1, T2, T3 Motor output terminals. Connect these terminals to a 3-phase
(U, V, W) induction motor of the proper voltage, current, and horsepower.
PA, PB Braking resistor output terminals. Connect to an external dynamic
braking resistor (available only on 30 HP and smaller drives).
FLA, FLB, FLC Programmable relay contact output. The contact rating is
250VAC - 2A. Default setting closes FLA-FLC and opens FLB-FLC
when protective function has been activated.
P24 Unregulated 24Vdc power supply (24Vdc, 50mA maximum). P24 is
protected by fused resistor found on the terminal board (see p. 5-1).
RCH(A & C) Programmable relay contact output
.
Standard setting closes
contact when an acc/dec is complete, or when the output
frequency is within a specified range. Contact rating is 250Vac - 2A.
LOW(A & C) Programmable relay contact output. Standard setting closes
contact when a preset low speed or a preset lower limit is
reached. Contact rating is 250Vac - 2A.
PP 10 VDC supply typically used to drive potentiometers. Wipers from
pots typically connected to "RR" or "RX" terminals.
FM* Programmable analog output. Outputs 0 - 1mA or 4 - 20mA (set by
JP4 on terminal board (see section 5.1)). This terminal can
be connected to an external analog meter. Use either an ammeter
rated 1mA DC/20 mA DC at full scale or a voltmeter rated 7.5Vdc at
full scale (true analog output). See page 9-23 for programming.
AM* Programmable analog output. Outputs 0 - 1mA or 4 - 20mA (set by
JP3 on terminal board (see section 5.1)). This terminal can
be connected to an external analog meter. Use either an ammeter
rated 1mA DC/20 mA DC at full scale or a voltmeter rated 7.5Vdc at
full scale (true analog output). See page 9-23 for programming.
FP Dedicated open-collector output. Pulses that are 48, 96, or
360-times the output frequency are available according to the
parameter settings (must connect external supply through pull-up
resistor to measure output).
* Do not make/break connections to these terminals with the drive powered.
