When installing a replacement Siemens PCU, there are some steps that you need to follow to get it configured which we have detailed below.

When installing a new Siemens Simodrive system, one of the first steps is to mount the drives in the cabinet. When you mount Siemens Simodrives, the modules must be arranged in a particular layout. The following criteria must be taken into account.
– Function of the module
– Cross section of the DC link busbar
Ohm Checking the Simodrive Power Section
Caution! It must be assured that power is removed and the DC Bus has drained to a safe level before any connections are removed or checked!
Check out our website for all Siemens and Simodrive products.
After you are sure that the DC Bus has safely discharged , a DVM on the Diode scale can be used to detect if a short circuit or open exists in the power section. Readings will vary with module size.
Note: P600 and M600 are the 600 V DC Bus connections. U2, V2 and W2 are the motor connections.
• Disconnect the P600, M600 bus bars, U2, V2 and W2 connections. This isolates the power module from the motor and DC Bus.
• Diode check between P600 and U2, then V2 then W2. There should be continuity with the – lead on P600 and the + lead on U2, V2 or W2. Readings should be open with the leads reversed.
• Diode check between M600 and U2, V2, W2. There should be continuity with the + lead on M600 and the – lead on U2, V2 or W2. Readings should be open with the leads reversed.
• Diode check between P600 and M600. There should be continuity with the + lead on the M600 and the – lead on P600. The reading should be open with the leads reversed.
• Diode check between U2, V2 and W2. All combinations should read open.
Note: If all readings are open the internal DC Bus fuse is open. If there is a 0Ω reading, there is a short in the power circuit.
Note 2: Because of the capacitance in the power circuit, resistance checks will indicate a charging effect. It is necessary to wait until the measurement has stabilized to determine if it is correct. If possible, it is best to use a DVM with a diode check.

The Simodrive 611 series is meant to be a converter system that is suitable for drive assemblies that can be combines with each other to enable fast and flexible synchronization of the drive performance. This will work for a number of axes on the machine and sets the Simodrive 611 productivity levels.
The Control Techniques Focus 3 drive is a single-phase analog drive for DC motors. The Focus 3 provides anywhere from ¼ to 5 horsepower and has 2 regenerative and 2 non-regenerative chassis units. Several measures can be taken to keep your drive functioning its best:
The Control Techniques Commander SE Microdrive series is an AC open loop vector that provides great flexibility as well as a small footprint. Although this series is reliable you may encounter one of the HF Trip codes listed below. These codes are a result of an internal error in the drive. Most often these trip codes can be resolved by powering down and allowing the drive sit for 5 minutes before powering up again.
If the HF Fault code does not clear then your drive will likely require a repair.
