24 / 37 page  TMC457 DATASHEET (V. 1.16 / 2009-Nov-25) 24 Copyright © 2009 TRINAMIC Motion Control GmbH & Co. KG Sequencer Configuration Register R/W Addr Bits Register Description Range 0x50 - (reserved) 0x51 - (reserved) 0x52 - (reserved) 0x53 - (reserved) RW 0x54 8…0 seq_mode bit 3…0: microstep table length Controls the number of microsteps per electrical period. For a stepper motor, the resulting microstep rate is ¼ of the table length. Values: 0: 8192 entries (Default), 1: 4096 entries, … 10: 8 entries, 11: 4 entries (full stepping) bit 8: sequencer stop W 0x55 23…0 dacscale_icntl bit 0..4: current_op default=% 00000000 00000000 10010000 bit 7: mixdecay_op bit 8..12: current_sb bit 15: mixdecay_sb W 0x56 2…0 stallguard_thrs StallGuard threshold 0…7 R 2…0 stallguard_ value actual StallGuard value reported by TMC249 0…7 R 0x57 2…0 driver_status Driver status read back information: bit 0 : tmcdrv_error (OT, UV, OCHS, OCB, OCA. i.e. all driver shutdown conditions) bit 1 : tmcdrv_otpw (over temperature pre-warning) bit 2 : tmcdrv_stall (StallGuard) 0x58 - (reserved) W 0x59 11…0 chop_clk_div chopper clock frequency register (for safety reasons a value below 96 can not be set) 96…818 default = 640 0x55: dacscale_icntl – Sequencer Configuration Register R/W Bit Function Value Description W 4…0 current_op 0…16 Motor current scale during operation (Default=16) Allows a current scaling by scaling the sine table entries before sending to the DACs or to the SPI stepper drivers. This function is available only for stepper motors. 16 = 100% 15...1 = 15 / 16 ... 1 / 16 0 = DAC disable / stepper driver disable 7 mixdecay_op 1 Mixed Decay Enable Operation (Default = 1) Enables the TMC23X / TMC24X mixed decay feature during motor operation. 12…8 current_sb 0…16 Standby current scale (Default=0) The motor is switched to the standby current after a delay time controller by stdby_delay. Same values as for current_op. 15 mixdecay_sb 1 Mixed Decay Enable Standby (Default=0) Enables the TMC23X / TMC24X mixed decay feature during motor stand still. |
