33.1.3. MAXIMUM PROGRAMMABLE SPEED VALUE
The maximum preset carrier frequency value also limits the maximum speed value to be programmed:
Max. programmable speed
→
rated speed * (maximum output frequency/rated frequency)
where the maximum output frequency results from the following:
C002
≤
5000Hz fout_max = C002 / 10
5000Hz < C002
≤
8000Hz fout_max = 500
8000Hz < C002 fout_max = C002 / 16
C002 is the maximum carrier frequency and the divisor is the min. allowable number of pulses per period.

(*) NOTE
The maximum output frequency is limited to the speed level programmed in parameters C028,
C029 [–32000 ÷ 32000]rpm. This results in Fout
max
= (RPM
max
*NPole)/120.
EXAMPLE:
When using a 4-pole motor and 30,000rpm are required, F
out
will be 1000Hz, so the performance requirements are
fulfilled.
On the other hand, if the same performance requirements are needed with an 8-pole system, 30,000rpm cannot be
obtained, as F
out
is 2000Hz. As a result, when using an 8-pole motor, the maximum allowable programmable speed is
15,000rpm[RPM
outmax
=(F
outmax
*120)/(number of motor poles)].
