COMMUNICATION PARAMETERS
(PARAMETERS AVAILABLE VIA THE COMMUNICATION LINK)
The communication link identifies ATV58 TRX drive controllers as a series of holding registers. The
tables in this section describe the content of the registers to show what information is available. The
registers are grouped by the following functions and are in numerical order:
• General configuration registers.
• Drive configuration registers.
• I/O configuration registers.
• Fault configuration registers.
• Adjustment registers.
• Control registers.
• Display registers.
• Special DRIVECOM registers.
General Configuration Registers
Word Code Units Description Possible Values or Range
W1
or 16#5FE0/1
CIC — Incorrect configuration
Upon power up, read CIC:
If CIC = 0: normal
If CIC ≠ 0: malfunction
Write CIC to 0 to return to factory settings.
Bit 0 = 0: Normal rating
Bit 0 = 1: Drive controller rating modified
Bit 1 = 0: Option card detection normal
Bit 1 = 1: Type of option card modified
Bit 2 = 0: Option card detection normal
Bit 2 = 1: Option card removed
Bit 3 = 0: Contents of EEPROM correct
Bit 3 = 1: Contents of EEPROM incorrect
Bits 4 to 15: Reserved
W3
or 16#5FE0/3
CFG — Macro-configuration.
Modification of this parameter reassigns other
parameters.
0 = HDG: Material handling
1 = GEN: General use
2 = VT: Variable torque (except Type FVC)
W4
or 16#5FE0/4
CRL 0.1 mA Minimum reference of input AI2 0–200 (0 to 20.0 mA)
W5
or 16#5FE0/5
CRH 0.1 mA Maximum reference of input AI2 40–200 (4.0 to 20.0 mA)
W6
or 16#5FE0/6
TCC — 2-wire/3-wire control via terminals. Modification of
this parameter will reassign the I/O.
0 = 2W: 2-wire control
1 = 3W: 3-wire control
W7
or 16#5FE0/7
TCT — Type of 2-wire control 0 = LEL: Level detection (0 or 1)
1 = TRN: Transition detection
(switching from 0 to 1 or 1 to 0)
2 = PFO: Transition detection with priority given to forward
over reverse
W8
or 16#5FE0/8
PST — STOP key has priority
(regardless of assigned control mode—i.e.,
terminal strip, keypad, or serial link)
0 = No
1 = Yes
W9
or 16#5FE0/9
STR — Speed reference storage
(+/–Speed)
0 = NO: Reference not saved
1 = RAM: Reference saved in RAM
2 = EEP: Reference saved in EEPROM
3 = SRE: Reference adjustment range limited by parameter
SRP (Type FVC only)
W10
or 16#5FE0/A
ADD — Drive address via the standard RS-485 serial link. 0 to 31
0 = Broadcasting without response
W11
or 16#5FE0/B
ORT — Drive power overrating for variable torque
applications
Modifying this parameter returns the following
parameters to the factory settings: UNS, NCR,
NSP, COS, TUN, ITH and IDC.
This parameter can be modified on ATV58 Type H
controllers when the macro-configuration (CFG,
W3) is set to variable torque (VT). See instruction
bulletin VVDED397047US (latest revision) for a
complete description. For ATV58 Type FVC
models, this parameter is always at 0.
0 = No (high overtorque)
1 = Yes (standard overtorque)
W12
or 16#5FE0/C
RIN — Inhibits operation of the motor in the reverse
direction (by logic input, analog input, serial
command, or REV key on the keypad display)
0 = No
1 = Yes
W13
or 16#5FE0/D
BSP — Manage low speed operation as a function of the
analog reference
0 = No: Normal
1 = BLS: Peak limiting (deadband)
2 = BNS: Base limiting (pedestal)
W14
or 16#5FE0/E
AOL 0.1 mA Minimum reference of analog output AO and AO1 0 to 200 (0 to 20.0 mA)
W15
or 16#5FE0/F
AOH 0.1 mA Maximum reference of analog output AO and AO1 0 to 200 (0 to 20.0 mA)
