8601 6040 CMDD R/W IEC 61800-7 control word
Identical to CMD (page 19).
bit 0: "Switch on": active at 1
bit 1: "Disable Voltage": active at 0
bit 2: "Quick Stop": active at 0
bit 3: "Enable Operation": active at 1
bits 4 to 6: Reserved: set to 0
bit 7: Fault state reset: active on rising edge 0 -> 1
bits 8 to 10: Reserved: set to 0
For "Access level" LAC (page 35) = L1 or L2:
bit 11 = 0: Forward direction command
bit 11 = 1: Reverse direction command
bit 12 = 0: No action
bit 12 = 1: Stop command depending on the Stt "Stop type" parameter
bit 13 = 0: No action
bit 13 = 1: Injection stop command
bit 14 = 0: No action
bit 14 = 1: Fast stop command
bit 15: Reserved: set to 0
For "Access level" LAC (page 35) = L3:
Factory assignments
bit 11 = 0: Forward direction command
bit 11 = 1: Reverse direction command
bit 12 = 0: No action
bit 12 = 1: Stop command depending on the Stt "Stop type" parameter
bit 13: No action
bit 14: No action
bit 15: No action
Bits 11 to 15 can be assigned to the following functions:
Ramp switching (rPS)
Fast stop (FSt)
DC injection (DCI)
2 preset speeds (PS2)
4 preset speeds (PS4)
8 preset speeds (PS8)
16 preset speeds (PS16)
2 preset PI references (Pr2)
4 preset PI references (Pr4)
Switching for 2nd current limit (LC2)
Switching, motor 2 (CHP)
External fault (EtF)
For example, to use bit 15 to switch the ramp, simply set the "Ramp switching" rPS
configuration parameter (page 39) to Cd15.
8602 6042 LFRD R/W Speed reference via the bus (signed value)
CiA 402: vl target velocity
IEC 61800-7: Nominal speed value
Unit:
• 1 = 1 rpm if bit 9 of CMI (page 20) = 0
• 1 ≈ 0.018 Hz (resolution 32767 points = 600 Hz) if bit 9 of CMI = 1
