Description
3.5 Operating modes and master control function
Mode
Manual operation local -
Supported by soft starter 3RW55 with firmware version V2.1 or higher and soft starter 3RW55 Failsafe with firmware version
1)
V1.1.0 or higher
Not possible for 3RW50, 3RW52, 3RW55 soft starters with firmware version earlier than V2.1 and 3RW55 Failsafe soft starters
2)
with firmware version V1.0.0. For soft starters 3RW55 from firmware version V2.1 and soft starters 3RW55 Failsafe with
firmware version V1.1.0 or higher if the digital inputs have master control by activating the "Manual operation local - input
controlled" bit in the process image output (PIQ). The PLC can fetch back control at any time.
3) Explanation in text below.
4) Possible for 3RW50, 3RW52, 3RW55 and 3RW55 Failsafe soft starters. For soft starters 3RW55 from firmware version V2.1 and
soft starters 3RW55 Failsafe with firmware version V1.1.0 or higher only if the input action "Operating mode manual - local"
has been parameterized and activated.
Connection abort
On failure of the bus connection or a CPU stop, the 3RW5 soft starter behaves as follows,
irrespective of the operating mode:
• 3RW50 soft starter: The 3RW50 soft starter behaves in accordance with the
parameter "Control via digital input" (Page 33).
• 3RW52 soft starter with firmware version earlier than V2.0.1: The 3RW52 soft starter remains
in "Automatic" mode or switches to "Automatic" mode.
Note
Response of 3RW52 soft starter in the event of bus connection failure or CPU stop
(3RW52 Soft Starter with firmware version earlier than V2.0.1)
To enable you to continue controlling the 3RW52 soft starter after failure of the bus
connection or CPU stop, you will need a 3RW5 HMI (accessory), which enables you to switch
to "Manual operation local" mode.
Without 3RW5 HMI you cannot control the 3RW52 soft starter until the bus connection has
been restored.
Alternatively, you can remove the 3RW5 communication module (Page 40). Then restore
the 3RW52 soft starter on the device to the factory setting, in order to switch to the "Manual
operation local ‑ Input controlled" mode.
• 3RW52 soft starter from firmware version V2.0.1: The 3RW52 soft starter behaves in
accordance with the parameter "Control via digital input" (Page 33).
• 3RW55 and 3RW55 Failsafe soft starters: The 3RW55 soft starter behaves in accordance with
the parameter "Response to CPU/master stop" (Page 64).
