Parameters
3010 STALL FUNCTION
This parameter defines the operation of the Stall function. This
protection is active if the drive operates in the stall region (see the
figure) for the time defined by 3012
STALL TIME. The “User Limit” is
defined in Group 20: LIMITS by 2017
MAX TORQUE 1, 2018 MAX TORQUE
2, or the limit on the
COMM input.
0 =
NOT SEL – Stall protection is not used.
1 =
FAULT – When the drive operates in the stall region for the time set
by 3012
STALL TIME:
• The drive coasts to stop.
• A fault indication is displayed.
2 =
ALARM – When the drive operates in the stall region for the time set
by 3012
STALL TIME:
• An alarm indication is displayed.
• The alarm disappears when the drive is out of the stall region for
half the time set by parameter 3012
STALL TIME.
3011 STALL FREQUENCY
This parameter sets the frequency value for the Stall function. Refer to
the figure.
3012 STALL TIME
This parameter sets the time value for the Stall function.
3017 EARTH FAULT
Defines the drive response if the drive detects a ground fault in the motor or motor cables. The drive monitors for
ground faults while the drive is running, and while the drive is not running. Also see parameter 3023
WIRING FAULT.
0 =
DISABLE – No drive response to ground faults.
Note: Disabling earth fault (ground fault) may void the warranty.
1 = ENABLE – Ground faults display fault 16 (EARTH FAULT), and (if running) the drive coasts to stop.
3018 COMM FAULT FUNC
Defines the drive response if the fieldbus communication is lost.
0 =
NOT SEL – No response.
1 =
FAULT – Displays a fault (28, SERIAL 1 ERR) and the drive coasts to stop.
2 =
CONST SP 7 – Displays an alarm (2005, I/O COMM) and sets speed using 1208 CONST SPEED 7. This “alarm speed”
remains active until the fieldbus writes a new reference value.
3 =
LAST SPEED – Displays an alarm (2005, I/O COMM) and sets speed using the last operating level. This value is the
average speed over the last 10 seconds. This “alarm speed” remains active until the fieldbus writes a new
reference value.
WARNING! If you select
CONST SP 7, or LAST SPEED, make sure that continued operation is safe when
fieldbus communication is lost.
3019 COMM FAULT TIME
Sets the communication fault time used with 3018
COMM FAULT FUNC.
• Brief interruptions in the fieldbus communication are not treated as faults if they are less than the
COMM FAULT TIME
value.
3021 AI1 FAULT LIMIT
Sets a fault level for analog input 1.
• See 3001
AI<MIN FUNCTION.
3022 AI2 FAULT LIMIT
Sets a fault level for analog input 2.
• See 3001 AI<MIN FUNCTION.
