Table 3-2 Ramp Time Jumper Behaviour - Siemens MICROMASTER 411 Operating Instructions Manual

Issue 03/01
Behaviour of the Ramp Time Jumpers
In Table 3-2 the behaviour of the Ramp Time Jumpers are explained:
Table 3-2 Ramp Time Jumper Behaviour
Status before action(s)
No jumper fitted
Ramp times have arbitrary setting
At least one Jumper fitted
Ramp times have arbitrary setting
At least one Jumper fitted
Ramp times have arbitrary setting
NOTE
The brake time is influenced by the setting for the ramp time (deceleration time).
The following relationship applies:
Braking time = P1121 (deceleration time) *
3.3.2 Control Circuit Jumpers
Control Jumpers (see Table 3-3) are provided for the following functions (fit jumper
to enable function). Jumpers can only be accessed when the cover is removed:
Pot = Run
Enables the control potentiometer as the Command Source (auto restart is
enabled).
24 V AIN
To change analogue input range from 0 –10 V to 0 – 24 V
DC Brake
To change Stop function from OFF1 to DC Brake.
Fan/Pump: M~n2
To change V/f curve from Linear to Quadratic curve.
60 Hz operation
To change motor default settings from 50 Hz to 60 Hz.
