Acceleration Time 1 (Ramp 1); Deceleration Time 1 (Ramp 1) - Reliance electric GV3000/SE Instruction Manual

P.001

Acceleration Time 1 (RAMP 1)

Parameter Range: V/Hz:
Vector: 0.1 - 999.9 seconds
Initial Setting: 20.0 (20 seconds)
Type: Tunable (at rest or during operation)
Refer to: P.004 Maximum Speed
P.005 Current Limit
U.017 Motor Top Speed
Description: Acceleration time in which the motor goes from zero to Motor Top Speed (Vector:
U.017) or Maximum Hz (V/Hz: P.004) after starting.
If the motor load inertia is high or the current limit (P.005) setting is too low, actual
motor acceleration time will be longer than the time set in P.001.
P.002

Deceleration Time 1 (RAMP 1)

Parameter Range: V/Hz:
Vector: 0.1 - 999.9 seconds
Initial Setting: 20.0 (20 seconds)
Type: Tunable (at rest or during operation)
Refer to: P.004 Maximum Speed
P.025 Stop Mode
U.017 Motor Top Speed
Description: Deceleration time is the time in which the motor decreases from Motor Top Speed
(Vector: U.017) or Maximum Hz (V/Hz: P.004) to zero speed when performing a
ramp stop (P.025 =1).
Note: Motor load inertia and input line conditions can extend the deceleration time to
a value greater than the preset time. With very fast deceleration times, regenerative
motor voltage may charge up the DC Bus voltage, causing a high bus voltage (HU)
fault trip.
To avoid a fault trip condition, either
- extend the deceleration time for a longer period, set Dynamic Braking Usage
(H.017) to 0, 2, 3 or 4.
- or, if a deceleration time faster than the non-trip value is required, replace the
power unit with one with an optional internal Dynamic Braking Unit or add an
external Dynamic Braking Unit, set Dynamic Braking Usage (H.017) to 1 or 5.
