Group 17: Ramp Generator - ABB DCS 500B Description

Group 17: RAMP GENERATOR

RAMP.[IN]
Input of RAMP GENERATOR-function block.
Source for the speed reference.
1701 FB_I: C4
RAMP.[RES_IN]
Input of RAMP GENERATOR-function block.
Used to set ramp input to zero.
1702 FB_I: C4
RAMP.[HOLD]
Input of RAMP GENERATOR-function block.
Used to hold the present ramp output value .
1703 FB_I: C4
RAMP.[FOLLOW_IN]
Input of RAMP GENERATOR-function block.
Used to make the ramp output to follow the ramp input value.
1704 FB_I: C4
RAMP.[FOLL_ACT]
Input of RAMP GENERATOR-function block.
Used to make the ramp output to follow the signal at RAMP.[SPEED_SET],
connected to SPEED ACT (12102) by default.
1705 FB_I: C4
RAMP.[RES_OUT]
Input of RAMP GENERATOR-function block.
Used to set ramp output to zero.
1706 FB_I: C4
RAMP.[T1/T2]
Input of RAMP GENERATOR-function block.
Selects the used set of ramp times:
0 = ACCEL1, DECEL1 and SMOOTH1 are used
<> 0 = ACCEL2, DECEL2 and SMOOTH2 are used.
1707 FB_I: C4
ACCEL1
Parameter of RAMP GENERATOR-function block.
The time in which the drive will accelerate from zero speed to nominal speed.
1708 FB_P: I2
DECEL1
Parameter of RAMP GENERATOR-function block.
The time in which the drive will decelerate from nominal speed to zero speed.
1709 FB_P: I2
SMOOTH1
Parameter of RAMP GENERATOR-function block.
The speed ramp output softening time (S-RAMP function).
The total time how long the softening function will last.
1710 FB_P: I2
ACCEL2
Parameter of RAMP GENERATOR-function block.
The time in which the drive will accelerate from zero speed to nominal speed.
1711 FB_P: I2
