Under / Over Voltage Trip Levels - Invertek Compact 2 Series User Manual

11.8. Under / Over Voltage Trip Levels

The following levels are not user adjustable, and define the operating voltage levels of the drive and brake chopper circuit.

Supply Voltage
100 – 115 Volts AC
110 – 240 Volts AC
200 – 240 Volts AC
380 – 480 Volts AC

11.9. Automatic Switching Frequency Reduction
The switching frequency selected in P-17 will be automatically reduced based on the heatsink temperature according to the data in section 4.5
Maximum Permissible Heatsink Temperature. In addition, switching frequency is reduced under the following conditions:
11.9.1. Output Frequency based Effective Switching Frequency Reduction
At low output frequency, Effective Switching Frequency is automatically reduced. Hysteresis is applied to prevent continuous switching. The
operation is according to the following table:
P-17
Effective Switching Frequency increases
when Output Frequency exceeds
Effective Switching Frequency reduces
when Output Frequency reduces below
11.9.2. Output Current Based Effective Switching Frequency Reduction
Effective Switching Frequency is automatically reduced based on motor load current as follows:

All OPC-2-240095 models:
o
If P-17 = 12kHz, 16 kHz, 24 kHz, Effective switching frequency is reduced to 8 kHz when motor current exceeds 10.45A (110%
of the drive rated current). Switching frequency will return to the value set in P-17 when motor current reduces below 7.6A
(80% of drive rated current)
o
If P-17 = 32kHz, Effective switching frequency is reduced to 8 kHz when motor current exceeds 10.45A (110% of drive rated
current). Switching frequency changes to 24 kHz when motor current reduces below 7.6A (80% of drive rated current).
Switching frequency will return to the value set in P-17 when motor current reduces below 6.7A (70% of drive rated current)

All other models:
o
Effective switching frequency is reduced to 8 kHz when motor current exceeds 140% of the drive rated current. Switching
frequency will return to the value set in P-17 when motor current reduces below 110% of drive rated current.

Note
1. Cable sizes shown are the maximum possible that may be connected to the drive. Cables should be selected according to
local wiring codes or regulations applicable at the point of installation
2. Refer to the UL Online Certification Directory for a list of UL Recognised products, File Number E226333
3. The integral overload protection does not provide branch circuit protection. Branch circuit protection must be provided in
accordance with applicable local regulations and the National Electrical Code.
4. Fuse type : UL JDDZ Class J
5. Where permitted, equivalent circuit breakers may be used
