Standard Specifications

Environmental Conditions

EnclosureIP20- Protected Chassis; IP65 – NEMA 4X (Indoor Duty)

Installation Location IP20Do not install in locations where product could be exposed to dust, corrosive gas, inflammable gas, oil mist, vapor, water drops or direct sunlight. There must be no salt in the atmosphere. Condensation must not be caused by sudden changes in temperature. For use at altitudes of 3300 ft. (1000m) or less without derating.

IP65 / NEMA 4X

Intended for use indoors to protect the enclosed equipment against splashing water, seepage of water, falling or hose directed water and severe external condensation. Installation should be less than 1000 meters (3300 feet) elevation, not in contact with corrosive gas, oil mist or direct sunlight.

Ambient Temperature-10°C to +50°C (+ 14°F to 122°F)

Ambient Humidity0 to 95% RH (non-condensing

Vibrationunder 1 G (9.8 m/s2)

Storage Temperature-25°C to +65°C (-13°F to 149°F)

Cooling Method0.25 to 1 Hp – Convection
2 Hp and greater – forced air (integral fan)

Input Frequency

Power System115VAC / 200-230VAC / 460VAC single or 3-phase, +10% to -15% V, 50-60 Hz +5% to -5% Hz

Output Frequency

SettingMaximum frequency: 0 to 200 Hz (in 1 Hz steps)

Accuracy (Stability)Digital setting: +0.1 % of maximum frequency (from -10°C to +50°C)
Analog setting: +1.0% of maximum frequency (at 25°C +1O°C)

Setting ResolutionDigital setting: 0.1 Hz (99.9 Hz or less), 1 Hz (100 Hz or more)
Analog setting: 0.06 Hz / 60 Hz


Control MethodSinusoidal PWM V/Hz control

Operation MethodKeypad operation: RUN or STOP key
Input signal: Forward/Reverse command, Command-to-stop command, Trip command (external alarm and alarm reset)

Frequency SettingKeypad operation: INC (UP) or DEC (DOWN) keys Built-in or external potentiometer of 1 to 5 k ohm (NEMA 4 only)
Analog input: 0 to 10 VDC / 4 to 20 mA DC / 0 to 20 mA DC
Multistep frequency: Up to 2 different frequencies can be selected using [OXO] input terminals

IndicationRunning: Digital indication of output frequency or output current (3-digit LED)
Tripped: Cause of trip by code (3-digit LED)

Acceleration/Deceleration Time0.1 to 999 sec. (independently adjustable acceleration and deceleration)

(V /F) Characteristics
6 selectable V /F patterns

Restart After Momentary Power FailureDrive restarts without causing the motor to stop when the automatic restart is selectable

Frequency LimiterHigh and low limits can be set for the output frequency between 0 to 200 Hz

Torque BoostTorque boost level adjustable (manual torque boost)

Starting Torque100% at 3 Hz


OverloadDetects overload to stop drive (150% for 1 minute)

Instantaneous OvercurrentDetects overcurrent due to overload on the drive output side to protect drive. Protects
drive in case of ground fault (when starting) and short circuit of output circuit.

Ground Fault OvervoltageDetects DC link circuit overvoltage to stop drive

Undervoltage OverheatingDetects abnormal temperature of cooling fan to stop drive

Undervoltage Motor ProtectionElectronic thermal overload detector

Alarm OutputOutputs a relay contact signal when any protective function is activated (SPDT contact, 250 VAC at 1A (30 VDC at 1A)
