Question: How can you preset memory modules for Servo Drives 9400 ready for operation in the field using a Servo Drive 9400 with a different power and the Engineer?
Answer:
Application:
Preparing an MMxxx memory module 'at your desktop' for a Servo Drive 9400 HighLine in a machine.
The memory modules can only be accessed via a Servo Drive 9400.
Typically, there are only Servo Drives 9400 with low power (e. g. E94ASxE0024 in the training cases) available in the office.
For some parameters of the Servo Drives, the value limitations depend on the power of the device. The operating system of the 9400 monitors compliance with the limit values. I. e. as part of a 'standard' parameter download to the axis, the Engineer cannot write any values that are higher than the value limitation to these parameters.
Parameters concerned:
C00022 'Maximum current': The upper limit value corresponds to the maximum device current (e. g. for E94ASxE0024 I_a; max = 6 A) C00174 'DC-undervoltage threshold': Single-axis devices E94ASxE0024 to E94ASxE1044 (Single Drive device sizes 1...7): C00174 = 210...400 V; single-axis devices E94ASxE1454 to E94ASxE6954 (device sizes 8S...10): C00174 = 400 V; multi-axis devices E94AMx (Multi Drive): C00174 = 15...400 V. C00018 'Switching frequency': For single-axis devices E94ASxE1454 ... E94ASxE6954 (device sizes 8S ... 10), the setting C00018 = 11 '16 kHz variable / drive-optimised' is not possible. C01199 'Increased power': For the single-axis devices E94ASxE0024 ... E94ASxE1044 and all multi-axis devices, you can only select the setting C01199 = 0 'Increased power off'. These devices do not allow operation at increased continuous power. From version 2.12 on, the L-force Engineer offers an additional option which allows you to write to these parameters without the value limitation becoming effective.
The attachment describes how to proceed to use this option for the specified application.
