9400HL and Dual-Use: Maximum output frequency depending on device variant and motor control mode

Question:

9400HL servo inverter:

Which device variant is to be used for license-free export to third countries (dual-use)?

What is the maximum output frequency achievable with the device variants?

Answer:

The maximum output frequency of the devices depends on the following factors:

Device variant, see table
Motor control mode (U/f-characteristic operation or servo control)
Inverter switching frequency (f = 2, 4, 8 or 16 kHz)

Limitation of the maximum frequency:

Device variant	U/f-characteristic operation	Servo control
E94A...	0..250 Hz (f = 2 kHz) 0..500 Hz (f = 4 kHz) 0..599 Hz (f >= 8 kHz)	0..250 Hz (f = 2 kHz) 0..500 Hz (f = 4 kHz) 0..1000 Hz (f = 8 kHz) 0..1999 Hz (f = 16 kHz)
E94B...	0..250 Hz (f = 2 kHz) 0..500 Hz (f = 4 kHz) 0..599 Hz (f >= 8 kHz)	0..250 Hz (f = 2 kHz) 0..500 Hz (f = 4 kHz) 0..1000 Hz (f = 8 kHz) 0..1999 Hz (f = 16 kHz)
E94C... (Dual-Use)	0..250 Hz (f = 2 kHz) 0..500 Hz (f = 4 kHz) 0..599 Hz (f >= 8 kHz)	0..250 Hz (f = 2 kHz) 0..500 Hz (f = 4 kHz) 0..599 Hz (f >= 8 kHz)

"Dual-Use":

Only the 9400 device variants marked "E94C..." are approved for export to third countries without a license.

Note:

On the nameplates of the E94A device variant, "0-599Hz" is printed as the output frequency range. This information refers only to U/f-characteristic operation, without feedback.

All devices marked "E94A..." and also "E94B..." do not meet the dual-use requirements for export to third countries without a license!
