CODE 119/92
DRIVE FOR ASYNCHRONOUS ROWAN SINGLE-PHASE MOTORS
with TACHOMETER
POWER RANGES
This drive is produced in two sizes on the same base:
- C119/92 for commanding of Rowan single phase motors up to 1HP provided with 10A protection
fuse.
- C119/92/2 for commanding of Rowan single-phase motors up to 2HP provided with 20A
protection fuse.
TECHNICAL CHARACTERISTICS
-
product
- Standard supply voltage: 230Vac ±10% 50/60Hz.
- Environmental temperature limit: -5°C +40°C.
- Stocking temperature from -25°C to +70°C.
- Working humidity limit from 5 to 95% (without condensation).
- Preset for ROWAN single-phase motors 2 - 4 - 6 pole, with 10Vdc at 1400rpm (20Vdc at 2800rpm)
tachometer.
- Input/output signals galvanically insulated from high voltage and connectable to PLC, programmable
logics, interface drives, etc.
- Input for tachometer with precision rectifier for functioning in both rotational sense.
- Motor revolution control adjustable through potentiometer (connected at 2 or 3 wires) or 0 /+10Vdc
signal.
- Motor torque limitation internally adjustable through trimmer, or externally through potentiometer
or 0 / +10Vdc signal.
- Input for pure contact (or NPN open collector transistor) for static run/stop command(12Vdc 2mA).
- Internal regulations through trimmer for:
> acceleration/deceleration ramp
> max speed
> minimum speed
> max torque
> minimum torque
> stability (anti-oscillation trimmer)
- Signalling by led illumination of the following functions:
> power on
> tachometer generator presence
> motor run
- Driving circuit protection with 0.5 A fuse (power protection to be performed externally).
- Cage-clamp terminal strip (on type 119/92 2 Hp power terminal strips are screw-clamp type).
- Standard open version with metal support and poly-carbonate cover, protection level IP 20
STANDARD CONFORMITY
Drive Code 119/92 is in conformity with the general IEC EN 60204-1 standard corresponding to the
essential safety requirement of the "Machinery Directive 89/392/EU", modified by the EU Directive
91/368 - 93/44 - 93/68. In particular, regarding the Electro-magnetic Compatibility (EMC) in industrial
environment, drive Code 119/92 is in conformity to the product CEI EN 61800-3 standard, for
"VARIABLE SPEED ELECTRICAL DRIVES" if connected to the network through a filtering device
as indicated by diagrams on page 9 and installed as written on page 8.
