Technical Specifications
Protective
functions
Phase loss
Refers to input/output phase loss protection.
Instantaneous
overcurrent
The AC drive stops when the output current exceeds 250%
of the rated output current.
Overvoltage
The AC drive stops when the DC voltage of the main circuit
is above 820 V.
Undervoltage
The AC drive stops when the DC voltage of the main circuit
is below 350 V.
Over‑
temperature
Protection is triggered when the inverter bridge gets
overheated.
Overload
Heavy load: The AC drive stops after running at 150% of
rated current for 60s.
Light load: The AC drive stops after running at 110% of
rated current for 60s.
Overcurrent
The AC drive stops when its current exceeds 2.5 x rated
current.
Braking
Refers to braking unit overload protection and braking
resistor short‑circuit protection
Short circuit
Refers to interphase short‑circuit protection and
protection against output short‑circuit to ground
Environment
Installation
environment
Indoor without direct sunlight, dust, corrosive gas,
combustible gas, oil mist, water vapor, drip, or salt.
Altitude
No derating is required for altitudes below 1000 m. For
altitudes above 1000 m, derate 1% for every additional
100 m. For altitudes above 3000 m, contact Inovance.
(Note: The maximum altitude for T1 models is 2000 m. For
altitudes above 2000 m, contact Inovance.)
Ambient
temperature
–10°C to +50°C. For temperatures between 40°C to 50°C,
derate 1.5% for every additional 1°C.
Humidity
Less than 95% RH (without condensation)
Vibration
Less than 5.9 m/s
