HVAC Application - Additional parameter information
Due to its user-friendliness and simplicity of use, the most parameters of the HVAC Application
only require a basic description which is given in the parameter tables in chapter 3.5.
In this chapter, you will find additional information on certain most advanced parameters of the
HVAC Application. Should you not find the information you need contact your distributor.
M3.1.1.7
M
OTOR
CURRENT
LIMIT
This parameter determines the maximum motor current from the drive. The parameter value
range differs from size to size.
When the current limit is active the drive output frequency is decreased.
NOTE:
This is not an overcurrent trip limit.

Coasting
The motor is allowed to stop on its own inertia. The control by the
drive is discontinued and the drive current drops to zero as soon
as the stop command is given.
1
Ramp
After the Stop command, the speed of the motor is decelerated
according to the set deceleration parameters to zero speed.

CS1: Start fwd pulse
CS2: Stop pulse
For 3-wire control (pulse control)
See Figure 8.
2
Start fwd pulse
Required to start.

AI1 threshold
The motor will start at the level set with parameter this parame-
ter and stop at the same -2% AI1 can also be used as fre-
quency reference in parallel.
