When starting the European wire rope electric hoist, it involves setting and adjusting multiple key time parameters, which are crucial for ensuring the safe and smooth operation of the equipment. The following are the key points for setting relevant time parameters:

1、 Start delay (t2)

Definition: The time interval from the frequency converter receiving the operation control signal to the motor starting to respond.

Function: To prevent on-site operators from directly switching the lifting mechanism from static to fast start, which may cause load impact, shaking, etc.

Setting suggestion: Set according to the recommended values of the device manufacturer, which can usually be found and adjusted in the parameter setting interface of the control system.

2、 Pre magnetization time (t3)

Definition: The time interval from the start delay signal t2 to the start of magnetic field orientation control in the frequency converter.

Function: Ensure that the motor receives sufficient magnetic field support during startup to achieve smooth starting.

Suggestion for setting: Also set according to the recommended values of the device manufacturer, and fine tune according to the load situation during actual operation.

3、 Demagnetization time (t4)

Definition: After the control operation signal is turned off, the frequency converter continues to maintain the time interval for outputting PWM signals to the motor, and then performs demagnetization processing.

Function: Ensure that the motor does not slip during deceleration and braking.

Suggestion for setting: Based on the deceleration characteristics and load conditions of the motor, set the demagnetization time reasonably to ensure that the motor can stop smoothly.

4、 Braking time (ts) and deceleration ramp time

Definition: Braking time refers to the time required for a motor to come to a complete stop from operating; The deceleration ramp time refers to the time curve required for the motor to decelerate from rated speed to zero speed.

Function: Both factors jointly determine the smoothness and safety of the motor during deceleration.

Suggested settings:

The braking time should be set according to the braking performance and load situation of the motor to ensure that the motor can completely stop within the specified time.

The deceleration ramp time should be set according to the inertia of the load and the deceleration requirements to avoid excessive impact and vibration of the motor during the deceleration process.
