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
32kHz
24kHz
16kHz
12kHz
8kHz

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
