0215 RAMP 1
Ramp 1: Fast acceleration time
4 sec
Possible settings: 1 – 250 (1000) sec
• Rapid acceleration may cause an error (OVERLOAD) during drive startup.
• Slow acceleration may cause a drop in outgoing pressure during startup.
0220
0220 RAMP 2
Ramp 2: Fast acceleration time
4 sec
Possible settings: 1 – 250 (1000) sec
• Rapid deceleration may cause error (OVERVOLTAGE).
• Slow deceleration may generate over pressure.
0225
0225 RAMP 3
Ramp 3: Slow acceleration time
70 sec
Possible settings: 1 – 1000 sec
• Rapid acceleration may lead to oscillation and/or an error (OVERLOAD).
• Slow acceleration may cause a drop in outgoing pressure during varying demand.
0230
0230 RAMP 4
Ramp 4: Slow acceleration time
70 sec
Possible settings: 1 – 1000 sec
• Rapid deceleration may lead to pump oscillation.
• Slow deceleration may cause pressure uctuations during varying demand.

Possible settings: 1.0 – 25.0 sec
Acceleration rate during startup until MIN. FREQUENCY [0250] is reached. Beyond the minimum frequency,
RAMP1 [0215] (fast acceleration ramp) applies.
• Rapid acceleration may cause error (OVERLOAD) during drive startup.
