VACON® 3000
Application Guide
If the brake opening command is given, but the contact of the brake feedback signal does not close in given time, a mechanical
brake fault shows (fault code 58).
7.249 (ID 1213) Quick Stop Activation
Location in the menu: P3.5.1.25 and P3.9.5.2
Use this parameter to select the digital input signal that activates a Quick Stop function. The Quick Stop function stops the drive
regardless of the control place or the state of the control signals.
7.250 (ID 1225) Motor Preheat Function
Location in the menu: P3.13.1
Use this parameter to enable or disable the Motor Preheat function. The motor preheat function keeps the drive and the motor
warm during the STOP status. In the motor preheat, the system gives the motor a DC current. The motor preheat prevents, for ex-
ample, condensation.

7.251 (ID 1226) Preheat Temperature Limit
Location in the menu: P3.13.2
Use this parameter to set the temperature limit of the Motor Preheat function. The motor preheat becomes active when the heat
sink temperature or the measured motor temperature goes below this level, and when P3.13.1 is set to 3 or 4.
7.252 (ID 1227) Motor Preheat Current
Location in the menu: P3.13.3
Use this parameter to set the DC current of the Motor Preheat function. The DC current for the pre-heating of the motor and the
drive in stop state. Activated as in P3.13.1.
7.253 (ID 1239) Jogging reference 1
Location in the menu: P3.3.6.4
Use this parameter to set the frequency references for the jogging function. With the parameters P3.3.6.4 and P3.3.6.5, it is possible
set the frequency references for the jogging function. The references are bi-directional. A reverse command does not affect the
direction of the jogging references. The reference for the forward direction has a positive value, and the reference for the reverse
direction has a negative value. The jogging function can be activated with digital input signals or from Fieldbus in bypass mode
with Control Word bits 10 and 11.

Description
The motor preheat function is disabled.
The motor preheat function is activated always when the drive is in the Stop state.
The motor preheat function is activated by a digital input signal, when the drive is in the Stop
state.
The motor preheat function is activated if the drive is in the Stop state, and the temperature
of the heat sink of the drive goes below the temperature limit that was set with parameter
P3.13.2.
The motor preheat function is activated if the drive is in the Stop state, and the measured
motor temperature goes below the temperature limit that was set with parameter P3.13.2.
You can set the measurement signal of the motor temperature with parameter P3.13.5.
To use this operation mode, you must have an option board for temperature measurement
(for example OPTBH).
