8.1 For your safety
WARNING
Electric shock due to charged capacitors.
Severe or fatal injuries.
• Observe a minimum switch-off time after disconnecting the supply voltage:
10minutes.
CAUTION
Risk of burns due to hot surfaces of the device or connected options, e.g. braking
resistors.
Injury.
• Provide for covers to secure hot surfaces.
• Install the protection devices according to the regulations.
• Check the protection devices on a regular basis.
• Let the device and the connected options cool down before you start working on
them.
INFORMATION
• For operating modes with encoder feedback, parameters must not be changed in
cycles faster than 2 seconds. This ensures that the encoders are initialized.
• The maximum output frequency in the VFC operating modes without encoder
feedback is 150 Hz.
• The maximum output frequency in the V/f operating mode and all operating
modes with encoder feedback is 599Hz.
• If the maximum output frequency is exceeded, error 08 "Speed monitoring" is dis-
played.
8.2 Relative cyclic duration factor (cdf)
The cyclic duration factor (cdf) is the ratio between the period of loading and the cycle
duration. The cycle duration is the sum of times of operation and times at rest and de-
energized. The typical value for the cycle duration is 10min.
